Abstract

This study investigated intermediate-spin states of Zr92 via the inverse reaction Be9(Kr,3n86)Zr92. Seven transitions were newly observed, and a lifetime was extracted for the 101+ state by analysis of Doppler-broadened line shapes of decay γ rays. A large B(E2) value was obtained for the transition from 101+ to 81+, and the magnitude was comparable to that for the deformed excited configurations in Zr94 that have recently been established. A possible origin for such collectivity is discussed qualitatively based on a phenomenological deformed rotor model. Moreover, a multipletlike structure that fits into the systematics for N=52 even-A isotones is revealed for the negative-parity yrast states.
