Description
Rapid shape change occurs in neutron-rich nuclei in the A∼100 region. Some of the nuclei in this region also exhibits ellipsoidal shape oscillations, known as gamma vibrations and linked to triaxiality and gamma softness. Furthermore, the two-phonon gamma-vibrations also provide tests of Pauli principle. To study of the evolution of the shapes and level structure, the 104Nb was investigated from two complementary experimental methods: i) high statistics triple- and four-fold gamma coincidences from 252Cf spontaneous fission using Gammasphere and ii) prompt gamma from the induced fission of the 238U+9Be reaction with isotopic fragment identification using the VAMOS++ and the AGATA spectrometers. Observation of multi-phonon gamma vibrations and shape coexistence of this odd-odd nucleus will be presented.
