GAMMA-RAY SPECTRA OF THE PRODUCTS OF FAST NEUTRON FISSION OF U235 AND U238 AT SELECTED TIMES AFTER FISSION

Abstract

Experimental measurements of the gamma-ray pulse height distributions due to the products of fast-neutron-induced fission of U235 and U238 are presented. The measurements were made at nine selected times after fission from 15 minutes to 3 days. Irradiation times and counting intervals were chosen to minimize saturation and decay effects. The experimental data were used to calculate 100 energy bin distributions of the absolute number of photons/ fission-sec. by means of absolute calibrations of the collimated NaI(T1) detector. The number of fissions in each sample was determined radiochemically. Machine computation was used extensively.
