Abstract
This study endeavors to develop an improved set of basis functions for nuclear shell-model calculations.The shell model,a well-established approach to understanding nuclear structure,typically employs the harmonic oscillator potential within the mean-field approximation.Given the extensive validation and consistency of harmonic oscillator results with experimental data,we propose a modification by incorporating a centrifugal term that converges toward the Davidson potential.This potential has been extensively studied,and we aim to extract relevant experimental data for the simplest cases in the shell model,namely one-particle and one-hole nuclei.A comprehensive comparison between the Davidson-based results and the harmonic oscillator calculations is presented to demonstrate the effectiveness of the new basis functions.
