AbstractA consistent set of statistical-model input parameters, validated by analysis of various independent data, makes possible the assessment of an $$\alpha $$ α -particle optical model potential [Phys. Rev. C 90, 044612 (2014)] also for nucleon-induced $$\alpha $$ α -emission within the $$A \sim 60$$ A ∼ 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 $$\alpha $$ α -emission beyond the statistical predictions has concerned the pickup direct interaction and Giant Quadrupole Resonance similar features.

Optical Model Potential

Allowing for important doorway state effects in analyses of proton elastic scattering from the light nuclei 14N and 160 enables an average geometry optical model potential to be determined, the strength parameters of which show a smooth behaviour with projectile energy.

Potential Parameters

The elastic scattering angular distributions of triton are calculated by the obtained systematic helium-3 global optical model potential parameters and compared with the available experimental data. These results show that the present global optical model potential can give a reasonable description of the elastic scattering of triton. The total reaction cross-sections of triton as a function of energy per nucleon are also further investigated and the reasonable results are presented.

Optical Model Analysis

The conventional optical model potential is used to analyze the p + 4He elastic scattering data in the energy range 100–1150 MeV. Both differential cross section and polarization data are reasonably fitted. The behavior of the volume integral of the real central potential as a function of energy is studied and is found to follow the same trend observed for heavier targets. The energy dependence of the imaginary central potential is also studied. The imaginary spin–orbit term is found to be important in this energy region. In some cases, the rising backward cross section is fitted by introducing a simple real exchange potential.
