Abstract
By use of a multichannel goniometer gamma-gamma angular correlations have been measured in97Tc. The obtained angular correlation coefficients are (energies in keV): 108.8–215.7A 2=0.38(3)A 4=−0.06(5) 754.0–215.7A 2=0.01(2)A 4=−0.01(2) 569.3–215.7A 2=0.25(1)A 4=0.00(2) 460.6–324.6A 2=0.08(2)A 4=−0.02(2) 645.2–324.6A 2=0.09(4)A 4=0.03(3).
These data are used to deduce theE2/M1 mixing-ratios of several transitions. The spin of the 785.0 keV level is found to be 5/2. The reduced transition strengths as well as relative transition strengths are calculated for some transitions and are compared with the predictions of a recent theoretical calculation.
