Absolute cross-sections for some (n, p), (n, α) and (n, 2n) reactions

Abstract The reactions Al 27 (n, α)Na 24 , Mg 24 (n, p)Na 24 , Si 28 (n, p)Al 28 , Co 59 (n, p)Fe 59 , Co 59 (n, 2n) Co 58 , Co 59 (n, α)Mn 56 , Ni 58 (n, p)Co 58 and Ni 58 (n, 2n)Ni 57 have been studied by an activation method from 12.5–21.0 MeV neutron energy. A method of calibrating well-type crystals to obtain absolute efficiency is described. The results for absolute cross-sections obtained by this method for the above reactions are compared with statistical model calculations in which the nuclear transmission coefficients have been derived from an average optical potential extracted from the scattering data.
