Abstract
The shape evolution of the Gd nuclei produced by the 124Sn+30Si reaction at a beam energy of 150 MeV has been studied as a function of spin by measuring the γ-ray decay of the giant dipole resonance. The nuclear deformation was extracted from the spectral shape and, independently, from the angular distribution with respect to the spin axis. Both measurements reveal that these nuclei remain prolate, with an increase in deformation as the spin increases. Sum-energy and multiplicity distributions have also been measured as a function of γ-ray energy.
