Nuclear Spectroscopic Investigations in the Decay of 1 ~ s mCd The energy levels in 11Sin at 934, 1 133, 1291, and 1419 keV weakly populated by ,6--decay from 11SmCd have been studied by angular correlation measurements using NaJ(T1)-detectors. The previously measured angular correlations of the (485-934) keV cascade--which is practically isotropic--and the (158-1 133)keV cascade were remeasured with higher accuracy. A 286 keV transition between the 1419 and the 1 133 keV energy levels was observed and the highly anisotropic angular correlation of the (286-1 133) keV cascade was also measured.

Gamma Gamma Directional Correlation Measurements in aa~CsThe lalCs decay has been studied by angular correlation measurements of the (404-216), (832-216), and (247-373) keV 7-cascades using NaJ(T1)-detectors in connection with a two parameter multi-channel analyzer. Unique spin assignments are obtained for the 216 (J~ = 3/2 +) and 373 (J~= 3/2 +) keV levels. A previously discussed value of J~= 5/2 + for the 1048 keV level is ruled out. The multipole character of the 404 keV transition is found to be E2 with less than 2% M1.
