Lifetime measurements of triaxial strongly deformed bands in {sup 163}Tm

With the Doppler Shift Attenuation Method, quadrupole transition moments Q{sub t} were determined for the two recently proposed triaxial strongly deformed (TSD) bands in {sup 163}Tm. The measured Q{sub t} values indicate that the deformation of these bands is larger than that of the yrast signature partners. However, the measured values are smaller than those predicted by theory. This observation appears to be valid for TSD bands in several nuclei of the region.

Pt have been measured using the Doppler-shift Recoil Distance technique. The results in both cases {\em viz.} a sharp increase in B(E2) values at very low spins, may be interpreted as resulting from a mixing between two bands of different quadrupole deformations.

High spin states in 103 Ag were investigated with the Gammasphere array by using the 72 Ge( 35 Cl, 2p2 n ) 103 Ag reaction at an incident beam energy of 135 MeV. A A J = 1 sequence with predominantly magnetic transitions and two nearly degenerate AJ = 1 doublet bands have been observed. The dipole band shows a decreasing trend in the B(M1) strength as function of spin, a well-established feature of magnetic bands. The nearly degenerate band structures satisfy the three experimental signatures of chirality in the nuclei; however, microscopic calculations are indicative of a magnetic phenomena.
