Description
Information about the proton-neutron interaction can be obtained from nuclear states particularly sensitive to the proton-neutron degree of freedom, of which low-lying isovector states are representatives. The main goal of this work is to test the existence of a low-lying isovector octupole excitation in Mo-96, a near-spherical nucleus, for which candidates were recently proposed, based on strong M1 transitions to the first excited 3- level observed in a prior neutron scattering experiment. A neutron capture experiment was performed at ILL Grenoble to test the experimental data the assignment is based upon. Several isovector excitations could be confirmed or identified. Other possible features of the low-energy structure of Mo-96 are discussed.
