Influence of resonances on 11B(n,g1)12B reaction rate
Within the framework of the modified potential cluster model with a classification of orbital states according to Young’s diagrams, the possibility of predicting the missing experimental data for the total cross sections of radiative n 11B capture to the first excited state of the 12B nucleus at 0.95 MeV (2+) for the reaction energy range from 10 meV (1 meV = 10 -3 eV) up to 7 MeV is considered. Based on the obtained total cross sections, which take into account resonances up to 5 MeV, the reaction rate is calculated in the temperature range from 0.01 to 10.0 T9. It is shown that low-lying resonances have a significant effect on the capture reaction rate.
