Chain yields from 19.1 MeV neutron-induced fission of sup 2 sup 3 sup 5 U

Chain yields for 35 mass chains were determined for the fission of sup 2 sup 3 sup 5 U induced by 19.1 MeV neutrons for the first time. Absolute fission rate was monitored with a double fission chamber; fission product activities were measured by HPGe gamma-ray spectrometry. Threshold detector method was used to measured the neutron spectrum in order to estimate the fission events induced by break-up neutrons and scattering neutrons from the environment. A mass distribution curve has been obtained
