Contribution of nuclear radial operators to β decay

Abstract

β decay is one of the most common processes in atomic nuclei. In this work we obtain expressions for contribution to the β decay half life from nuclear radial operators. Once the analytical expressions have been obtained, we evaluate them in the three single-particle orbitals of the s-d shell, which is the relevant configuration space for the 23Ne β decay into 23Na, and estimate the impact of nuclear radial operators in this decay
