On Single Particle Energies and Nuclear g Factors

TL;DR

This paper investigates the single particle energies and nuclear g factors in Sn isotopes, focusing on the low-lying states in ^{101}Sn and their impact on the spectra of higher isotopes, addressing a dispute over state ordering.

Contribution

It analyzes how different assumptions about the ground state in ^{101}Sn influence the spectra of subsequent Sn isotopes.

Findings

The J=5/2^{+} and J=7/2^{+} states are separated by 0.18 MeV.

Dispute exists over the ordering of these states.

Spectra vary depending on the assumed ground state.

Abstract

If we add one neutron to doubly magic ^{100}Sn, we can associate the low lying states in^{101} Sn with single particle states.The the J=5/2^{+} and J= 7/2^{+} states are identified as d_{5/2}and g_{7/2}states respectively...They are separated by an energy of 0.18 MeV.Unfortunately there is a disputeas to the ordering of these states.We examine how the 2 scenarios-- J=5/2^{+} ground state or J=7/2^{+}ground state-- affect spectra of higher Sn isotopes .
