We have indirectly determined the {sup 237}Np(n,f) cross section over an equivalent neutron energy range from 10 to 20 MeV using the surrogate reaction {sup 238}U({sup 3}He,tf). A self-supporting {approx}761 {mu}g/cm{sup 2} metallic {sup 238}U foil was bombarded with a 42 MeV {sup 3}He{sup 2+} beam from the 88-Inch Cyclotron at Lawrence Berkeley National Laboratory (LBNL). Outgoing charged particles and fission fragments were identified using the Silicon Telescope Array for Reaction Studies (STARS) consisted of two 140 {mu}m and one 1000 {mu}m Micron S2 type silicon detectors. These results were compared with the {sup 237}Np(n,f) cross section data from the direct measurements, the Evaluated Nuclear Data File (ENDF/B-VII.0), and the Japanese Evaluated Nuclear Data Library (JENDL 3.3) and found to closely follow those datasets.
