Search for the Jacobi shape transition in rapidly rotating nuclei

Abstract

We have studied the continuous gamma radiation from reactions of {sup 48}Ca beams on targets of {sup 50}Ti, {sup 64}Ni, {sup 96}Zr, and {sup 124}Sn at very high angular momentum. In all but the heaviest target, the nuclear moments of inertia rise rapidly with increasing angular momentum and the data suggest that the gamma ray energies may reach a maximum value. Whether this arises from a gradual transition towards a highly deformed Jacobi-like shape, or from other effects, is unclear.
