Title: Triaxiality in {sup 105}Mo and {sup 107}Mo from the low to intermediate spin region

Abstract

The nuclear structure of the odd {sup 105}Mo and {sup 107}Mo isotopes was reinvestigated in the present work. The excited levels of {sup 105}Mo were studied by observing prompt {gamma} rays emitted after the spontaneous fission of {sup 248}Cm with the EUROGAM2 multidetector array. The already well-studied level structure of {sup 107}Mo was also completed by a search for microsecond isomers. For this purpose, this nucleus was produced by the thermal-neutron-induced fission reaction at the ILL reactor, in Grenoble. We have shown that the experimental level energies and the {gamma}-decay patterns are well reproduced by simple particle-rotor calculations, assuming that these nuclei have an asymmetric shape. The shapes of the odd and even Mo are compared in the neutron range N=62-66.
