Benchmark calculation of no-core Monte Carlo shell model in light nuclei

TL;DR

This paper applies the Monte Carlo shell model to no-core calculations in light nuclei, demonstrating that it closely matches full configuration interaction results with minimal discrepancies.

Contribution

It introduces the application of the Monte Carlo shell model to no-core calculations in light nuclei, showing its accuracy compared to traditional methods.

Findings

Monte Carlo shell model results agree within a few percent with full configuration interaction.

The method provides a viable alternative for no-core calculations in light nuclei.

Abstract

The Monte Carlo shell model is firstly applied to the calculation of the no-core shell model in light nuclei. The results are compared with those of the full configuration interaction. The agreements between them are within a few % at most.
