The 10,11B(n,p)10,11Be reactions at En=96 MeV

Double-differential cross sections of the 10,11B(n,p)10,11Be reactions have been measured at 96 MeV in the angular range 0°–30° for excitation energies up to 35 MeV. The spectra have been decomposed into different multipolarities using sample angular distributions calculated within the distorted-wave Born approximation. From the identified Gamow–Teller strength, Sβ+ values were obtained for 10B and 11B. At higher excitation energies, the spectra are dominated by L=1 strength in broad distributions with maxima around 22 and 12 MeV in 10B and 11B, respectively.
