Lifetimes of low-lying members of a DeltaI = 1 band in Ph-196 and of the superdeformed (SD) band in Nd-135 have been measured with the EUROBALL spectrometer and with the Cologne plunger apparatus at Legnaro. The (DY)-D-164(S-36,4n)Pb-196 and the Pd-110(Si-30,5n)Nd-135 reactions were used to populate the states of interest at beam energies of E-36 S=168 MeV and E-30 Si=148 MeV, respectively.

Abstract

Lifetimes of low-lying members of a DeltaI = 1 band in Ph-196 and of the superdeformed (SD) band in Nd-135 have been measured with the EUROBALL spectrometer and with the Cologne plunger apparatus at Legnaro. The (DY)-D-164(S-36,4n)Pb-196 and the Pd-110(Si-30,5n)Nd-135 reactions were used to populate the states of interest at beam energies of E-36 S=168 MeV and E-30 Si=148 MeV, respectively. The experimental data were analyzed with the differential decay-curve method (DDCM). Measured B(M1) values are consistent with the picture of the shears mechanism which has been used to describe the DeltaI = 1 bands in Pb-196. It was found that in Nd-135 the decay out of the SD band is caused by accidental level mixing.
