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

The total cross section of the B-10(p,gamma)C-11 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 B-10 target with protons and, after stopping the beam, detecting the 511 keV gamma rays emitted from the beta(+) decay of C-11, using two LaBr3:Ce detectors. In addition to the total cross sections, astrophysical S factors were also calculated at each energy.
