Variation of Single-Particle Energies: Scaling Behavior for the Spectrum of ${}^{48}$Cr

Abstract

We perform shell model calculations for ${}^{48}$Cr using GXPF1A and FPD6 interactions by varying single particle energies. We find a scaling behavior which leads to the finding that many different sets of interactions with vastly different single particle energies can give almost identical results for the yrast spectrum of ${}^{48}$Cr
