Production ofB11andB10by Proton Spallation ofC12

Abstract

Measurements of the ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$ and ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$ spallation production in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ are presented. These cross sections are related to theories on the origin of the elements lithium, beryllium, and boron.
