Some Neutron Reaction Cross Sections for ^{111, 112}Cd, ⁸⁷Sr, and ⁵⁸Ni

The cross sections for the reactions ¹¹¹Cd(n,n′)^111mCd, ¹¹²Cd(n,2 n)^111mCd, ⁸⁷Sr(n,n′)^87mSr, ⁵⁸Ni(n,p) ^{58m + g}Co, ⁵⁸Ni(n,2n) ⁵⁷Ni, and ⁵⁸Ni[n,d) + (n,np) + (n,pn)] ⁵⁷Co have been measured by the activation method. Measurements were performed in the energy regions from 2.2 to 3.5 MeV and from 13.7 to 14.8 MeV. The cross sections obtained for the ¹¹¹Cd and ⁸⁷Sr reactions indicate that both these isotopes should prove useful as neutron flux monitors. The cross sections obtained for the ⁵⁸Ni reactions are in good agreement with the results of recent investigations.
