New level density parameter beyond Egidy-Bucurescu’s systematics

Nuclear level density (NLD) within the back-shifted Fermi gas (BSFG) model of nuclear structure.

This preprint focuses on refining existing methodologies for calculating level density parameters (LDPs) within the established BSFG model. The authors compile and analyze experimental data, comparing various existing parameterizations and proposing refined fits. The core assumptions and framework of the BSFG model itself are not challenged, and the work aims to improve accuracy and predictive power within the existing paradigm. This aligns with Kuhn's characterization of "normal science," where research efforts concentrate on puzzle-solving within the dominant paradigm. The preprint does not propose alternative theoretical frameworks or challenge fundamental assumptions about NLD or the BSFG approach. It seeks incremental improvements rather than revolutionary changes, firmly placing it within the normal science stage.
