Abstract

The cross sections for the reactions 27Al(n,α) 24Na and 56Fe(n,p)56Mn were precisely measured via the activation technique at En=14.6MeV. The monoenergetic neutrons were produced through D-T reaction at the Cockcroft accelerator of CIAE. The neutron fluence was determined by the associated α-particle method. The absolute activities of the reaction products were measured by a 4πβ-γcoincidence device. Taking account of various corrections, the cross sections of 27Al(n,α)24Na and 56Fe(n,p)56Mn are obtained as 113.2 ± 1.5 mb and 111.4 ± 1.5 mb, respectively.
