Validation of an optical potential for incident and emitted low-energy α-particles in the A ∼ 60 mass range

A consistent set of statistical-model input parameters, validated by analysis of various independent data, makes possible the assessment of an alpha-particle optical model potential [Phys. Rev. C 90, 044612 (2014)] also for nucleon-induced alpha-emission within the A similar to 60 mass-number range. The advantage of recent data for low-lying states feeding is taken as well. Consideration of additional reaction channels leading to increase of the alpha-emission beyond the statistical predictions has concerned the pickup direct interaction and Giant Quadrupole Resonance similar features.

Automated summary

This study validates a consistent set of statistical-model input parameters through analysis of various independent data, enabling the evaluation of an alpha-particle optical model potential, including for nucleon-induced alpha-emission within the A similar to 60 mass-number range. It also considers additional reaction channels leading to increased alpha-emission beyond statistical predictions, particularly focusing on features similar to the pickup direct interaction and Giant Quadrupole Resonance.
