Abstract
The nuclear precession of106Sn in the 6+ state was measured relative to that of108Sn by the IPAD method: θ(6+;106Sn)/θ(6+;108Sn)=1.06(33). Available data on the 6+ state in108Sn giveg (6+;106Sn)=− 0.14(9), which is consistent with the seniority ν=2 configuration: ({ie133-01}). B(E2; 10+→ 8+) was measured to be 6.4(10) W.u. for106Sn and 0.62(5) W.u. for108Sn. This difference could not be explained by the ν≦4 configurations. The {ie133-02}→13− transition turned out to be an M1/ E2 mixed transition and so the yrast I=14 state was identified with a state of the νh11/2 band.
