Statistical Hauser-Feshbach Model Description of (n, α) Reaction Cross Sections for the Weak s-Process

NUCLEAR REACTIONS ¹⁷O, ¹⁸F, ²²Na, ²⁶Al, ³³S, ^37,39Ar, ⁴⁰K, ⁴¹Ca, ⁵⁹Ni, ⁶⁵Zn, ⁷¹Ge(n, α), E=0.001-30 MeV; ¹⁷O(n, α), E=0.4-2000 keV; ²⁶Al(n, α), E=0.1-1000 keV; ³³S(n, α), E=5-1000 keV; ³⁷Ar(n, α), E=0.01-1000 keV; ⁴¹Ca(n, α), E=0.4-150 keV; calculated reaction σ(E) using two different statistical Hauser-Feshbach model, with experimental masses, and nuclear level densities from Fermi gas model (TALYS-a), and nuclear masses and level densities calculated with the Skyrme functional (TALYS-b). Comparison with results in NON-SMOKER, TENDL-2019, ENDF-B-VIII, JEFF-3.3 and BROND-3.1 libraries, and with available experimental data. ¹⁷O, ¹⁸F, ²²Na, ²⁶Al, ³³S, ^37,39Ar, ⁴⁰K, ⁴¹Ca, ⁵⁹Ni, ⁶⁵Zn, ⁷¹Ge(n, α), kT=0.008-1000 keV; calculated reaction σ(temp) averaged over the Maxwell-Boltzmann distribution. ²²Na, ²⁶Al, ³³S, ^37,39Ar, ⁴⁰K, ⁴¹Ca, ⁵⁹Ni, ⁶⁵Zn, ⁷¹Ge(n, α), kT=0.007-1000 keV; calculated Maxwellian averaged cross sections (MACS) as function of temperature, and compared with results in NON-SMOKER, ENDF-B-VII.1, JEFF-3.1, JENDL-4.0, ROSFOND-2008 and CENDL-3.1 data libraries. ⁴¹Ca, ⁵⁹Ni, ⁶⁵Zn, ⁷¹Ge(n, α), kT=30-210 keV; calculated reaction σ(temp) averaged over the Maxwell-Boltzmann distribution. ¹⁷O, ¹⁸F, ²²Na, ²⁶Al, ³³S, ^37,39Ar, ⁴⁰K, ⁴¹Ca, ⁵⁹Ni, ⁶⁵Zn, ⁷¹Ge(n, α), kT=30-210 keV; calculated σ(temp). Relevance to the s-process nucleosynthesis.
