摘要

Exclusive measurements of high-energy. rays have been performed in Ba-124 and Ba-136 at the same excitation energy (similar to 49 MeV) to study the properties of the giant dipole resonance (GDR) over a wide N/Z range. The high-energy. rays are measured in coincidence with the multiplicity of low-energy gamma rays to disentangle the effect of temperature (T) and angular momentum (J). The GDR parameters are extracted employing a simulated Monte Carlo statistical model analysis. The observed. gamma-ray spectra of Ba-124 can be explained with prolate deformation, whereas a single-component Lorentzian function which corresponds to a spherical shape could explain the. gamma-ray spectra of Ba-136. The observed GDR width in Ba-136 is narrower compared to that of Ba-124. The statistical model best-fit GDR cross sections are found to be in reasonable agreement with the thermal shape fluctuation model (TSFM) calculations. Further, it is shown that the variation of GDR width with T is well reproduced by the TSFM calculations over the temperature range of 1.1-1.7 MeV.
