Summary
Excitation functions have been determined for the spallation and fission reactions induced in plutonium isotopes by 20 to 50 Mev helium ions. The method employed consisted of cyclotron bombardments of plutonium oxide followed by the chemical isolation and alpha or beta counting of radioactive reaction products. Formation cross sections are given where possible for the curium and americium spallation products corresponding to (α,n), (α,2n), (α,3n), (α,4n), (α5n), (α,p), (α,pn or d), (α,p2n or t), and (α,p3n) reactions in Pu²³⁸ , Pu²³⁹, and Pu²⁴². Fission yield curves and fission cross sections for Pu²³⁸ and Pu²³⁹ serve to define the characteristics of the (α,f) reaction for plutonium isotopes. Chemical procedures are outlined for the separation of both spallation and fission product elements in a sequence of operations performed on the entire dissolved target.
