ABSTRACT* Data are g-*ven from a study of spectrally luminescent characteristics of
silicate glasses activated by praseodymium ions. The trivalent praseodymium cation
has two 4f electrons and a comparatively small number of singlet (ISO, IG4, ID2, 1166)
and triplet (3H, 3F, 3P) levels. Absorption and luminescence of crystals and glasses
activated by praseodymium are*detexmined by forbidden transitions between these levels
The absorption spectra of the glasses were studied in the spectral region below IV us-
ing an SF-4 spectrophotometer, and in the region of longer waves on the automatic SV-
-50 spectrophotometer made by the Shimadzu Comp~ny. The luminescence spectra were re-
corded on installations with diffri6i1E'ii6C_c;d7rciators and FEU-38 photomultipliers,
a cooled FEU-22 photomultiplier and a cooled lead sulfide photoresistor. Electronic
EPPV-60-3H and PS1-02 potentiometers were used for recording the spectra. The lumi-

nescence excitation source was generally a mercury lamp with a 436 my glass filter.
A diffraction monochromator was used for excitation in some cases. The luminescence
lifetime was measured either with a pulsed tau-meter in combination with a diffractiol
monochromator to isolate certain sections of the luminescence spectrum, or by an ul-
tratau-meter and a set of light filters. The first method gave the best s3ectral re-
solution while the second gave the highest accuracy for determination of T . Absorp-
tion and luminescence.spectra are given for glass containing 0.2% Pr2O3. The experi-
mental data show a high probability for nonradiative transitions from P levels to,
lower-lying states, particularly to the ID2 level which is the initial state for a
number of intense radiative transitions in the red region of the spectrum. When the
temperature is reduced to 770K, there Is a redistribution of intensities in the lumi-
nescence spectrum of trivalent praseodymium favoring the blue-green bands. It Is
shown that there is a nonradiative transfer of excitation energy between praseodymium
ions and between praseodymium and ytterbium ions which results in concentration quencl
ing of Pr luminescence in the first case and luminescence sensitization of Yb in the
second. Quenching due to nonradiative energy transfer from praseodymium to ytterbium
is less effective when the temperature Is reduced to 770K which may be due to a reduc-
tion in the overlapping of levels. Orig. art. has: 4 figures, 2 tables. 14

ABSTRACT: An investigation was made ~f the transfer of excitation energy in silica
glass activated simultaneounly with two and three rare-earth ions, The investigatior,
of the interaction of Yb-Nd, Yb-Pr, and Nd-Pr ion pairs was based an the dependence,
of intensity and the duration of rare-earth ion luminescence on the concentration.
The pair interaction is rather complicated: the nonradiative energy transfer can
proceed in several ways and all three activators can serve as donors and acceptors
of excitation energy. In the case of the interaction of Yb-Nd pairs with the simul-
taneous activation of glasses-with Nd3t' and Yb 3+ ions, a sensitized luminesce.-Ice of
of ytterbium results from the nonradiative transfer of energy from neodymium ions in
the 4F 3/2 state to the unexcited ytterbium ions.' This leads to an attenuation of -the
intensity and to a shortening of the luminescence duration of neodymium. A reverse
enern transfer from ytterbium to neodymium, does not occur. In Yb-Pr the intcractfjon~;
of Yb + and Pr3+ ionB is of a dual nature. On the one hand, during excitation in the

absorption band of Pr3* ions a sensitized luminescence of Yb34* takes place. On the
other hand, conditions exist for the resonance transfer of excitation energy from I
Yb3"' to Pr3+- Thus, the praseodymium is simultaneously a sensitizer and a quencher_
for ytterbium luminescence. The quenching effect of praseodymium exceeds its sensi
tizing effect on,ytterbium. In Nd-Pr*a similar phenomenon takes place during
interaction of the activator pair Nd and Pr. The presence of Nd3+ ions provokes
quenching' of Pr3* lumineaccnee in bands which are bound with transitions from. the ID2
level. The praseodymium ions on their part render a strong quenching effect upon the
luminescence of neodymium. The authors thank P. P. Feofilov for 'his constant interesti -i,%,

TITLE OFTre-V scence of the Front of a Shook Wave.
PERIODICAL Zurn.eksp i teor.fis,~1,fasc.6, 1105-1105 (1956)
Issued: ; / 1957
In the course of experiments carried out on a ballistic device a luminescence
of the front of the shook wave was observed in several gases (i.ECKEFUAAN,
R.SCHWARTZ, Phys.Rev., A.�I, 912 (1952) although the temperature behind the
shook wave in a multiatomic gas did not suffice for the excitation of
luminescence. The following hypothesis may serve to explain this phenomena:
on the occasion of a collision of the molecules on the front of the shook wave,
the energy of the direted motion goes over into the subordinated thermal
energy.' The computations carried out by C.ZENER (Phys-Rev-.a, 556 (1931))
showed that after about 10 collisions a MAXWELL velocity distribution of mole-
cules occurs, whereas the rotation- and oscillaticn degrees of freedom are
practically left without excitation ("frozen-in"). on this occasion the entire
energy goes over only to the degrees of motion of the progressing motion, and
the local temperature of a gas becomes much higher than the temperature of
the equilibrium established in the course of events.
After the.degrees of freedom of the progressing motion the electron levels and
the degrees of freedom of rotation are excited. According to the individual
properties of the molecules, at first the electron levels, and then the degrees

Zurn.eksp. i teor.fis,31,fase.6,1105-1105 (1956) CARD 2 / 2 PA - 1854
of freedom of rotation, or else both together can be excited. In either case
local temperature remains higher than equilibrium temperature. It is just by
this energy distribution which does not correspond to equilibrium, that the
observed-luminescence can be explained, overmore as it is the f r o n t of
the shook wave that is luminescent, where the degrees of freedom of oscilla-
tion are-not,yet excited in view of the fact, that for their excitation from
104 to 105 shocks are necessary.
Further excitation of the degrees of freedom of rotation and oscillation leads
to a decrease of gas temperature. which then tends towards equilibrium temper-
ature and to an extinction of the luminescence. The more rapidly the interior
degrees of freedom are excited on this occasion, the narrower will be the
zone of luminescence. In gases with multiatomic molecules the domain of lumi-
nescence will therefore be narrower than in monoatomic gases, where tempera-
ture drop is due only to a decrease of luminescence.
The above is,a translation of this short report.

ABSTRACT: In supersonic motions in great heights the free length of path
LM is comparable with the measurements L of the moving body.
Gases for which this occurs are denoted by the author as
"weakly thinned gases". The boundary layer equations are set
up in the weakly thinned gas according to Prandtl's method,
they differ, however, from the usual Frandtl equations by the
occurrence of higher derivatives in the velocities and in the
temperature; the pressure gradient in the direction of the nor-
mal is different from zero which is expressed by additional
terms. The boundary conditions for the derived equations are
derived according to the kinetic theory; these are generalized
conditions as they were set up for supersonic motions by
Maxwell and Smoluchove-ti. The limits of applicability of the
investigated equations are given with respect to the height
Card 1/2 as well as with respect to the velocity.

ABSTRACT There is no possibility to obtain analytic formulae for gas para-
meters if the variable specific heat cp is taken into account and
it is therefore necessary to apply numeral solutions. In T,1956 Vol
21, number 6 the author shows a hiethod for the consideration of
the dependence of the specific heat 0 on T and p as a consequen-
ce of oscillation excitation, dissociltion and ionization of the
gas on the occasion of its passage through an impact wave. This
method is also applied here. The following can be said on account
of the calculations: 1.- The taking into account of the variable
specific )feat leads to a drop of brake temperature and to an in-
crease of the density compared with the corresponding Talaes for
a constant specific heat. In the case of Mi-12 (ratio of the -ve-
locity of increasing gas flow and the velocity of sound) these va-
lues differ by almost look. 2, Change of brake pressure at thelex-
pense of variable specific heat in the case of Mi
