Evaluation of fusion-evaporation cross-section calculations

TL;DR

This paper compares fusion-evaporation cross-section calculations from five models with experimental data across various nuclei, finding that averaging models improves agreement, highlighting model limitations and potential for refinement.

Contribution

It introduces a method of averaging multiple models' predictions to better match experimental data in fusion-evaporation cross-section calculations.

Findings

All models tend to overestimate experimental data.

Averages of models' predictions align more closely with experiments after scaling.

Refined analysis performed for the 100Sn region.

Abstract

Calculated fusion-evaporation cross sections from five different codes are compared to experimental data. The present comparison extents over a large range of nuclei and isotopic chains to investigate the evolution of experimental and calculated cross sections. All models more or less overestimate the experimental cross sections. We found reasonable agreement by using the geometrical average of the five model calculations and dividing the average by a factor of 11.2. More refined analyses are made for example for the 100Sn region.
