We propose a microscopic approach to study giant dipole resonance (GDR) by analyzing the response of nuclear density to dipole radiation. This is done through the calculation of single-particle wavefunctions using a triaxial Woods-Saxon potential. We compare the results with a macroscopic approach for GDR and explain the recent experimental data for Nd144-152 and Sm-152 nuclei. Additionally, we analyze the fine structure of GDR cross-section using the continuous wavelet transform (CWT) framework and explain its origin.
We present a microscopic approach for giant dipole resonance (GDR) where the linear response by the nuclear density to the dipole radiation is represented through the single-particle wavefunctions calculated with a triaxial Woods-Saxon potential. We follow a microscopic-macroscopic approach to estimate the nuclear deformation with the same potential. We explain the recent experimental data for even-even nuclei Nd144-152 and Sm-152 and present a comparison with the macroscopic approach for GDR. We highlight the cases where the results from the microscopic approach are sensitive to the change in single-particle configuration despite no change in shape and mass but with a change of two protons in a mid-shell region. We also present the fine structure analysis of the GDR cross-section using the continuous wavelet transform (CWT) framework and elucidate the origin of such fine structures.
