Title: Identification of Mixed-Symmetry States in an Odd-Mass Nearly Spherical Nucleus

Abstract

The low-spin structure of {sup 93}Nb has been studied using the (n,n{sup '}{gamma}) reaction at neutron energies ranging from 1.5 to 3 MeV and the {sup 94}Zr(p,2n{gamma}){sup 93}Nb reaction at bombarding energies from 11.5 to 19 MeV. States at 1779.7 and 1840.6 keV, respectively, are proposed as mixed-symmetry states associated with the {pi}2p{sub 1/2}{sup -1}x(2{sub 1,MS}{sup +},{sup 94}Mo) coupling. These assignments are derived from the observed M1 and E2 transition strengths to the 2p{sub 1/2}{sup -1}x(2{sub 1}{sup +},{sup 94}Mo) symmetric one-phonon states, energy systematics, spins and parities, and comparison with shell model calculations.
