Excited low-spin states of {sup 92}Zr have been studied with the (n,n{sup '}{gamma}) reaction. Comprehensive data on the electromagnetic decay of states with excitation energies up to about 3.8 MeV in particular, lifetimes, {gamma}-ray branching ratios, multipole mixing ratios, and absolute transition strengths have been obtained. The detailed spectroscopic information about the low-spin level scheme enables us to address the predominant proton-neutron symmetry for low-spin states of {sup 92}Zr. These data are compared to those of corresponding states in the N=52 isotone {sup 94}Mo and to a shell model calculation using {sup 88}Sr as an inert core. However, neither a purely collective picture nor the restricted shell model calculation yields a fully satisfactory description of the observed structures.
