Abstract
High-spin states in doubly odd166Tm were investigated by means of in-beam g-ray spectroscopy techniques using the multidetector array GASP. Excited states of166Tm were populated using the160Gd(11B,5n) reaction at a beam energy of 61 MeV. Known rotational bands have been extended to higher spins and their configurations have been discussed. Alignments, band crossing frequencies, and electromagnetic properties have been analyzed in the framework of the cranking model. Signature inversion in theph9/2^ni13/2structure is dis-cussed. Calculations in the framework of the particle rotor model withp2ninteraction included have beenable to reproduce the inversion.E1 decay modes were observed in competition withE2 intraband transitionsFile | Dimensione | Formato | |
