“…According to Nilsson diagram the ground state of 75yb has the character 7/2-[514] while the 114 keV level of ~75Lu has the character 9/2 + [404]. Bogdan [11] developed the necessary theoretical expressions for both the relativistic and non-relativistic matrix element parameters and obtained the following result with a deformation parameter, 6=0.28. x= -3.74, u=0, Z=I.…”

The angular correlation of the 7/2-~9/2 + lt4keVX ,7/2 + is measured at Ea = 300 keY and found to be A2(/~,7)=0.108_+0.028. The result is combined with the data on longitudinal polarisation nuclear orientation to obtain the nuclear matrix elements which would give a simultaneous fit to all experimental data. The matrix elements thus obtained have predicted the/~ spectrum shape correction factor. The sizes of the matrix elements indicate a cancellation effect in vector matrix elements which explains deviation from i-approximation. From the ratio of higher order matrix elements, 2, the deviation from the CVC ratio due to Fujita is found and thus the importance of off-diagonal elements in H C is noted. The experimental matrix elements are compared with the modelpredicted ones.
