Title: Cross-section measurements of neutron-induced reactions on GaAs using monoenergetic beams from 7.5 to 15 MeV

Abstract

Cross-section measurements for neutron-induced reactions on GaAs have been carried out at twelve different neutron energies from 7.5 to 15 MeV using the activation technique. The monoenergetic neutron beams were produced via the {sup 2}H(d,n){sup 3}He reaction. GaAs samples were activated along with Au and Al monitor foils to determine the incident neutron flux. The activities induced by the reaction products were measured using high-resolution {gamma}-ray spectroscopy. Cross sections for five reaction channels, viz., {sup 69}Ga(n,2n){sup 68}Ga, {sup 69}Ga(n,p){sup 69}Zn{sup m}, {sup 71}Ga(n,p){sup 71}Zn{sup m}, {sup 75}As(n,2n){sup 74}As, and {sup 75}As(n,p){sup 75}Ge, are reported. The results are compared with the previous measurements and available data evaluations. Statistical-model calculations, based on the Hauser-Feshbach formalism, have been carried out using the TALYS and the COH3 codes and are compared with the experimental results.
