Using both the absolute and relative surrogate techniques, the ²³⁶U(n,f) cross section was deduced over an equivalent neutron energy range of 0 to 20 MeV. A 42 MeV ³He beam from the 88 Inch Cyclotron at Lawrence Berkeley National Laboratory was used to perform a (³He,α) pickup reaction on targets of ²³⁵U (J^π=7/2⁻) and ²³⁸U (J^π = 0⁺) and the fission decay probabilities were determined. The ²³⁵U(³He,αf) and ²³⁸U(³He,αf) were surrogates for ^{233 …}
