TEXT: In the lutetium fraction forming in the cour7se of 'an irradiation
of tantalum with 660-Mev protons, conversion lineo'';were;discovered, which
had a period of two hours. The authors investigated the;:lutetium isotope
to which these lines belong. For this.purpone thoy.uaed'a~p-spectromster
with double focusing, the magnetic field was measured by means of proton
resonance, and calibration was carried out according to exactly known
lines. Recording was carried out by means of two daiger.:HUller counters.
Three conversion lines with a period of (2.15 + 0-20) hours were dis-
covered; closer details are given in Table 1. By comparing the energy
differences between these -three lines with X-ray data, It was found that
the Lu-isotope goes over into an ytterbium isotope. Prom the close study

come to the conclusion that the required isotope with a'period of 2.15

TITLE: Conversion electrons of the short-lived ~platinum and tungsten
isotopes
PERIODICALi Akademiya nauk 8SS11. Izvestiya. 86riya*fizicheskaya, v. 26,
no. 1, 1962, 120 - 124
TEXT: The conversion electron spectra of the platinum and the tungsten
fractions were measured by a P-spectrometer with double focusing by the
method of nuclear resonance in the intervals 68 - 106 kev, and 70 -90
kev, respectively. The neutron-deficient platinum and tungsten isotopes
were produced by bombarding gold with 660-Mev protons. Table 1 gives the
parameters of the 16 lines obtained for the plalinum~fraction. 7 of
these lines have been newly discovered. The 106.43-ke* transition cannot
be attributed to one of the Pt isotopes but only to an Ir isotope. The
intensity ratio of the lines L and LIII suggests ar. E2 or E3-type,
transition. Also for the 110.T6-kev transition in at iridium nucleus

the isotope on whose decay transition takes place cannot be determined,
due to its insufficiently accurate half line. The L II LIII LIII lin.es
with the energies 96.71, 97.25 and 98.87 kev of the liO.10-kev transition
have a half life of (20�0.3) hr. The ratio of the line intensities of
inner conversion on the L-subshells suggests a transition of type El, or
E2+M1. Also the 93.94-kev transition mentioned in 1960 at the X:
Soveshchaniye po yadernoy spektroskopii (Tenth Congress on Nuclear
Spectroscopy) in Moscow takes place in an iridium! nucleus , The three
conversion lines with the half life (2.6tO.6) hr and the energiab 72A,
74.3, and 83.2 kev which the authors studied in the 70 - 90-kev~~S;pectral
range belong to the decay of W176 or W177. The first,two lines are
