Description

Experimental data for the 27Al(n,2n)26Al cross section have never been reported in the neutron energy range above 15 MeV, since the detection of the long-lived 26Al (half-life of 7.2x105 yr) necessitates an intense high-energy neutron source and highly sensitive detection method. We have measured the 27Al(n,2n)26Al cross section in the energy range of 14--36 MeV by using a semimonoenergetic neutron beam from the Be(p,n) reaction. The activity of 26Al was measured by the accelerator mass spectrometry method and we found that the cross section has a maximum value of 95 mb in the neutron energy range of 20--24 MeV
