Abstract
TheΒ-γ circular polarization asymmetry for three nuclides has been measured using a special polarimeter developed at Karlsruhe. The results of the measurements are
Nuclid | A | Transition |
|---|---|---|
Fe59 | −0158±0.007 | β0.47−γ1.10 MeV |
Sb124 | +0.278±0.013 | β0.62−γ1.69 MeV |
Ru102 | −0.107±0.011 | β0.22−γ0.50 MeV |
From the measured values of Fe59 and Sb124 the Fermi- and effective Coulomb matrix elements are calculated. From the asymmetry coefficient of Ru103, and internal conversion measurements of other authors we are able to deduce the spin of the 537 keV level in Rh103 to 5/2+ or 7/2+. The multipolarity of the 497 keVγ-rays in Rh103 is found to be E2 with a small mixture of M1.
