Abstract

The structural transitions of nuclei under extreme conditions of high spin and temperature is examined. The giant dipole resonance (GDR) built on excited states is studied in Samarium nuclei. The static collective model for GDR is used in this work to obtain the resonant energies and the corresponding peak cross sections for 152Sm nuclei. Equilibrium shapes are obtained by finite temperature version of the cranked Nilsson - Strutinsky shell correction method. The shape correlation between the GDR cross section and the predictions by CNS method is made. Results show that the GDR cross section reflects the shapes obtained by CNS method and the theoretical GDR cross sections are in agreement with the experimental data.
