Neutron capture cross section measurements for 237Np have been conducted with neutrons with energy ranging from thermal energy to several hundred keV. A Time of Flight (TOF) method using NaI(Tl) detectors was employed for this measurement and the data were analyzed based on a pulse-height weighting technique in order to derive the neutron capture cross section.
