Contribution

It advances understanding of nuclear spectra by examining schematic interactions with many degeneracies in a specific shell model space.

Findings

Spectral degeneracies are characterized in schematic interactions.

The work provides insights into the structure of nuclear energy levels.

It bridges previous experimental data with theoretical models.

Abstract

In previous works we examined the spectra for systems of 2 protons and 2 neutrons, in a single j shell calculation, by obtaining matrix elements from experiment. More recently we considered schematic interactions in the same model space. We continue in this vein here. The present work and the former can be regarded as 2 bookends on a bookshelf.
