Cross section measurements of the 10 B( p , γ ) 11 C reaction between 2.0 and 6.0 MeV

The total cross section of the ${}^{10}$B($p$,$\\ensuremath{\\gamma}$)${}^{11}$C reaction has been measured for bombarding proton energies between 2.0 and 6.0 MeV in 500 keV steps for the first time. This reaction is important for potential next-generation boron fueled nuclear reactors. The total cross section was measured by activating a ${}^{10}$B target with protons and, after stopping the beam, detecting the 511 keV $\\ensuremath{\\gamma}$ rays emitted from the ${\\ensuremath{\\beta}}^{+}$ decay of ${}^{11}$C, using two LaBr${}_{3}$:Ce detectors. In addition to the total cross sections, astrophysical $S$ factors were also calculated at each energy.
