AN EXPERIMENTAL STUDY OF FISSION IN THE ACTINIDE ELEMENTS

PDF Version Also Available for Download.

Description

The results of a recent experimental investigation of the fission properties of some actinide elements are presented. The study includes: fission fragment kinetics, fission neutron spectra, prompt gamma rays from fission, and delayed neutrons from fission. The kinematic distributiou of the fission fragment modes of Th/sup 229/. Pu/sup 240/, P/sup 241/, Cm/sup 242/, Cm/sup 244/ , Cf/sup 252/, and Fm/sup 254/ were determined using a high resolution back-to- back ionization chamber. The fission neutron spectra of U/sup 233/, Pu/sup 241/, and Cf/sup 252/ were measured from 0.2 to 10.0 Mev. The prompt fission gamma spectrum of Cf/sup 252/ was measured ... continued below

The fission neutron spectra of U/sup 233/, Pu/sup 241/, and Cf/sup 252/ were measured from 0.2 to 10.0 Mev. The prompt fission gamma spectrum of Cf/sup 252/ was measured from 0.075 to 10.0 Mev using single and double crystal scintillation spectrometers. The periods and yields of the delayed neutron groups emitted in the fission of Cf/sup 252/ were measured. The integrated field per fission was found to be ~ 1/100 that U/sup 235/. (W.D.M.)
