Sr88(p, n)Y88Reaction in the Proton Energy Range from 4.4 to 8.0 MeV

Abstract

The ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}(p, n){}_{}{}^{88}{}_{}{}^{}\mathrm{Y}$ reaction cross section was measured in the proton bombarding energy range between the ($p, n$) threshold and 8.0 MeV. The neutron detector was a 24-in. cube of polyethylene with four ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ neutron counters inserted radially toward the center of the cube where the target of ${}_{}{}^{88}{}_{}{}^{}\mathrm{Sr}$O was placed. Analysis of the data was carried out by means of direct solution of the Lane equations and by application of a method similar to that due to Robson. In both analyses, the calculated excitation functions were compared with the ($p, p$) and ($p, n$) data. It is shown, in a practical sense, that the two methods of analysis give essentially equivalent results.
