Measurements of Neutron Fission Cross Sections of ²³⁷Np, ²⁴⁰Pu, ²⁴¹Pu, ²⁴²Pu, ²⁴⁴Pu, and ²⁴¹Am at 14.7 MeV

Neutron fission cross sections of ²³⁷Np, ²⁴⁰Pu, ²⁴¹Pu, ²⁴²Pu, ²⁴⁴Pu, and ²⁴¹Am have been measured at 14.7-MeV neutron energy using a different technique. Fission fragments were detected with a silicon detector, and the flux of neutrons on the sample was determined by the standard activation technique using the ²⁷Al (n, ⁴He)²⁴Na reaction. The present results are in good agreement with recent measurements reported in the literature.
