Abstract

This study investigates the electric quadrupole transition probabilities (B(E2)↑), deformation parameter ( ), and intrinsic quadrupole moments (Q₀) for transition levels in even-even Cadmium isotopes, Cd⁹⁸ to Cd¹³⁰) (Z=48). The calculations were performed for the (0⁺ → 2⁺, 2⁺ → 4⁺, 4⁺ → 6⁺, and 6⁺ → 8⁺) transition levels by the Global Best Fit method.

The study reveals systematic trends in these nuclear parameters across the isotopic chain and with increasing transition levels. A notable finding is the comparatively lower values of B(E2)↑, , and Q₀ for isotopes with neutron numbers approaching or at magic numbers, such as (N=50 for Cd⁹⁸ and N=82 for Cd¹³⁰). This observation indicates a reduction in collective behavior and a tendency towards a more spherical nuclear shape in these regions, consistent with established nuclear shell effects.
