Activation Cross Sections for theF19(n,2n)F18,Na23(n,2n)Na22,Mn55(n,2n)Mn54,In115(n,2n)In114m,Ho165(n,2n)Ho164m,In115(n,n)In115m, andAl27(n,α)Na24Reactions

Abstract
The (n,2n) activation cross sections of F19, Na23, Mn55, In115, and Ho165 have been measured in the neutron energy range from 12.7 to 19.4 MeV. In addition, the activation cross sections for the In115(n,n)In115m and Al27(n,α)Na24 reactions have been measured in the energy range from 1.0 to 19.4 MeV and from 6.1 to 19.4 MeV, respectively. Most of the measurements were made relative to the fission cross section of U235. The experimental (n,2n) cross sections have been compared with the predictions of the semiempirical cross-section theories of Pearlstein and of Gardner.
