Description

In this work, new results from a series of particle-evaporation experiments on nuclei spanning a wide mass range, including the fission-product region, are presented. The measurements include energy spectra of emitted neutrons and charged particles obtained over a range of excitation energies.
The experimental data are compared with statistical-model calculations performed with commonly used reaction codes. A detailed assessment of model performance is provided, with particular emphasis on the sensitivity to the choice of level-density models. Systematic trends in the extracted level-density parameters across different nuclei are discussed, highlighting regions where current models reproduce the data well and where significant deviations remain.
These results provide new benchmarks for improving reaction modeling and offer insight into one of the most important nuclear parameters—the nuclear level density. The identified systematics contribute to a more reliable description of compound-nucleus reactions and are relevant for applications in nuclear astrophysics, reactor physics, and nuclear data evaluations.
