摘要

Background: Many nuclear structure calculations, even for full configuration interaction approaches, are performed with input Hamiltonians represented in a truncated model space. These often require consistent transformations of the operators to account for the missing physics beyond the active space, so that several recent efforts have been devoted to find compatible derivations of the effective operators. The effective charges employed in the shell-model calculations, and fitted to reproduce experimental data, can be seen as the phenomenological counterpart of such renormalization for electromagnetic operators.
