Prompt Fission Neutron Multiplicities for $^{241}$ Pu using Surrogate Reactions

ORAL

Abstract

The prompt fission neutron multiplicity for \textsuperscript{241}Pu was measured at the Texas A$\&$M University Cyclotron using the NeutronSTARS array. Due to the short half-life ($14.3$ yrs) of \textsuperscript{241}Pu, inelastic scattering on \textsuperscript{242}Pu with 55 MeV alpha particles was used as a surrogate. The average neutron multiplicity ($\bar{\nu}$), and the neutron multiplicity distribution for equivalent neutron energies up to 20 MeV are discussed and reported.
