Cross-section measurements for the (n,p) and (n,alpha) reactions on Na-23 and for the (n,p) reaction on Mg-26 at the neutron energies from 13.6 to 14.9 MeV

Abstract

Cross sections were measured at neutron energies from 13.6 to 14.9 MeV for the reactions Na-23(n,p)Ne-23 and Na-23(n,a)F-26, and Mg-26(n,p)Na-26 leading to short-lived products. The production of short-lived nuclei and the spectra accumulation have been carried out by cyclic activation method. Corrections were made for the effects of gamma ray attenuation, coincidence summing, pulse pile-up, dead time, neutron flux fluctuations and scattered low energy neutrons.
