Abstract

This work proposes a theoretical estimation for the cross section of the proton-boron fusion reaction for the first excited level of the beryllium intermediate nucleus, based on nuclear theories for isolated resonances and continuum reaction cross sections that acceptable reproduce available experimental data. This result might help to analytically deconvolute the alpha particles contribution from the total dose in the mixed field of the irradiation in biological tissue, and might also be useful for applications in aneutronic energy sources research.
