MASS DISTRIBUTION IN 22 MeV NEUTRON-INDUCED FISSION OF ~(235)U

The chain yields of 29 product nuclides are determined for the fission of 235 U induced by 22 MeV neutrons. Fission rate is monitored with a double fission chamber. Fission product activities are measured by HPGe γ ray spectrometry. Time of flight technique is used to measure the neutron spectrum in order to estimate fission events induced by break up neutrons and scattering neutrons. A mass distribution curve is obtained after correction for background neutrons.
