We investigate the electric dipole (E1) structure properties of the deformed Nd146-152 nuclei in the giant dipole resonance (GDR) region within the framework of the quasiparticle random-phase approximation (QRPA). Translational and Galilean invariance (TGI) QRPA with separable isovector dipole-dipole residual interaction have been employed for the calculations. We have computed the photoabsorption cross-section and then we have compared with the experimental data. Our calculations revealed that while the photoabsorption cross-section shows a Lorentzian line in the neighborhood of spherical geometry, it starts to shift to an asymmetric shape by increasing deformation in Nd146-152 isotopes by increasing neutron number. In addition to this, we have also observed that the splitting of the B(E up arrow) strength distribution and the separation between K = 0 and K = 1 branches are increasing. We have calculated the contribution of the electric and magnetic parts of total dipole strength up to 20MeV for the nuclei of interest. This calculation shows that the electric part dominates the total dipole strength and (IK)-K-pi = 1(-)1 excitation dominates the electric part. |
