The ( n, α) and ( n, p) reactions in silicon and the ( n, p)reaction in aluminium at energies up to 5·6 MeV

Abstract

Cross-sections are given for the n, p and n, α reactions in silicon and the n, p reaction in aluminium at energies up to 5·6 MeV. The silicon measurements were made using a silicon semiconductor detector as the target and detector, and the aluminium measurements were made by β-counting the 27Mg activity produced in aluminium foils. The results are compared with previous measurements. It is shown that in measuring excitation functions in this energy region, the use of a silicon semiconductor detector is a convenient method of measuring the incident neutron energy.
