A theoretical study on the effective quadrupole deformations of ^100-128Cd isotopic chain

NUCLEAR STRUCTURE ^{100,102,104,106,108,110,112,114,116,118,120,122,124,126,128}Cd; calculated energy levels, J, π, B(E2), deformation parameters using a simple interacting boson model (IBM) to Cadmium (Cd)isotopic chain to obtain the quadrupole transition rates and effective deformation. U(5) and O(6) dynamical symmetry limits of this model to classify the considered states.

Properties of giant dipole resonances within an extended pairing model with a focus on spectral statistics

NUCLEAR STRUCTURE ³²S, ⁴⁰Ca, ⁵²Cr, ⁵⁶Fe, ^58,60Ni, ^70,72,74,76Ge, ⁷⁶Se, ⁸⁶Kr, ⁸⁸Sr, ⁹⁰Zr, ^116,124Sn; analyzed experimental spectral and statistical features of negative- and positive-parity dipole states using random matrix theory (RMT) and Berry-Robnik distribution (BRD) methodologies; calculated Poisson distributions and integrands for Giant-dipole resonances for the nearest-neighbor spacing distribution (NNSD). Calculations based on spd-interacting boson model (IBA), with the pairing correlations from solutions of the Bethe ansatz equation.
