3» Circular polarization of gamma rays after capture of pola­
rized neutrons in S» Ca, Ti, Cr» Co, Hg and Fb.
K. Abrahams and W. Ratynski .
The circular polarization of gamma rays after capture of
polarized thermal neutrons in natural targets of S, Ca, Ti,
Cr, Co, Hg and Pb has been measured using two Ge(Li) detec-
3 3
tors with a volume of 15 cm and 30 cm , respectively. As a
source of polarized neutrons a system of 52 cobalt mirrors,
each one meter long, was used. Circular polarization was
measured by transmission through two 10 cm long cylinders
of magnetized permendur. Every 10 sec. the neutron spin was
reversed. The measuring time per sample was on the average
two weeks. Several new spin assignments could be made and
many old spin assignments could be confirmed.
