I Teoret. Fiz., '35 178 1958~ and H. A. Tolhock (cf.,
Rev. Mod hys., 26, 27~1 195 ), a transverse polariza-
tion of -electrons escaping in a plane perpendi,!ular
Aear spin, takes place dur
to the nu Ing the decay
of polarized nuclei. The authors have investa'ated
the correlation between the transversely polarized
electron and circular6y polarized Y-quanta formed
in the Xdecay of CO U( ^,100 tL Cu). A case was
studied where the electron momentum P lies In the
plane perpendicular to the momentum Tt of Y -quantum,
which possesses circular polarization 0- The spin

TITLE: Py-P:)larization correlation in the P-decay of Sc46
PERIODICAL: Zhurnal eksperimentallnoy i. teoreticheskoy fiziki, v. 40,
no. 1 , 1961 , 10-12
TEXT: Within the framework of experiments made for the purpose of verifying
the T-invariance of the 0-decay, the Py-correlation in the decay of polar-
ized neutrons and the Py-correlations in the decay of orientated nuclei has
already been measured, and it was found that (with an accuracy of 4
15-3CV6
no imaginary part occurs in the 0-interacticn ffamiltonJan. The amount o~
this correlation in these experiments depends on the imaginary part of the
interference VA termsj as, howeverp an S- and T-admIxture could hitherto
not be excluded, this should also be teken into account. This was the pur-
pose of the present paper. By trying to estimac the amount of Im(VT, SA)f
the correlation between the transverse polarization of the electron and the
circular polarization of the gamma quantum were experimentally determined.

Py-P.7larization correlation B1021B204
The experimental arrangement is shown in Fig. 2. A theoretical study of
the correlation coefficient K for allowed transitions (according to
A. Z. Dolginov) shows that K depends on the degree of interference of the
Gamav-Taller and the Fermi matrix elements. Thus, Sc.4 was chosen aB a
source owing to its high degree of interference of the matrix elements. The
electrons goming from the source (S) are collimated on a bismuth film
(0-5 mg/cm4), scattered through -1350, and recorded by means of a scintil-
lator, which is connected with the photomultiplier via a light pipe. Owing
to the azimuthal asymmetry, which is connected with Mlott scattering, the
,,, r-O _v
beam of the scattered electrons is polarized in the direct P P P,
1 #21 1 ( 'a
the momentum of the electron before, and P. that after scattering). In cr-
der to increase counting intensity, Circu lar geometry wqs used. The circu-
lar polarization of '-,he I-quanta was measured by means of the method of the
Compton forward scattering on magnetized iron. The outputs of the photo-
multiplier of the 0- and y-detectors were connected in fa3t-slow coincidence
with 2-v . 1.8-10-8 sec. From the measured results A - 2(1 1- 12)1(,1+,2)1

be K - 0.00 + 0.06. The experiments were repeated ty means of a thick
scatterer ('5mg/cm 2), from which it followed that the experimental arrange-
ment had no eaymmetry. Thus, it was found that, as

is Im(VT,AS) . 0 with a statistical accuracy of- 30~j. For the purpose of
checking the exper mental method, also Py correlation experiments were
carried out on sc4~ and C060, and results were obtained, which showed good
agreement with those obtained by other authors. The authors finally thank
A. Z. Dolginov for discussions and for his interest, 0. M. Saltykovskiy,
V. V. Andryukevich, and A. V. Kurakin for the experimental assistance.

TEXT: The 0-t' correlation between the mom6ntum of the P-electron and the
circular polarization of the 1.327 May/'quantum in the allowed branch of
the Eu152m 0-decay with a O-electron end-point energy of 560 key is
measured. This P-decay, whose frequency of occurrence among all decays of
152m 152
EU is 1.2%, leads to the 1.515 May excited I- state of Gd . The
measurements were made with an apparatus described earlier (V. M.
Lobashov at al., ZhETF 41, 1433, 1961), then used for investigating the
similar Pr144 decay by an analogous experimental procedure. The Eu152m
souroe was made of about 1OOpg/CM 2 europium oxide on an Al backinl/foil,
irradiated in the FTI AN SSSR reactor. The value of A -201 12 (11+1 2)

For the transitions 0 , I ~ 0 a correlation coefficient of +1.00 is
to be expected, but for the transitions I- P, I- r,O+ a correlation
coefficient of the observed magnitude is possible. It is concluded that
spin and parity of the Eu152a isomeric state are 1- instead of the pre-
viously accepted value 0 . The reliability of the applied experimental
procedure is confirmed by the fact that Or, correlation measurements in the
0 decays of Co 60 and Au 198 (V. M. loobaohov et al.t ZhETF 42, 358, 1962)

Determination of the spin of k;u B163/B186
have given results in good agreement with those of other authors. It is
important to know the spin and parity of the Eu152m isomeric state in
connection with the experiment of Go.Ldhaber et al. (Phys. Rev. 109, 101r),
1958) whereby the polarization of the neutrino from the K decay was
measured. Goldhaber's main result i. e. his conclusion on the chirality
of the neutrino, is not affected, but the expected greater accuracy from
152m
further ouch experiments with Eu to dete'rmine the polarization of the
neutrino is diminished. There is 1 figure.
