Charge distribution in the spontaneous fission of {sup 252}Cf. Determination of fractional cumulative yields of {sup 133m}Te and {sup 123g}Te

Technical Report:

Abstract

The fractional cumulative yields (FCY) of {sup 133m}Te and {sup 133G}Te in the spontaneous fission of {sup 252}Cf have been determined by the radiochemical method. The values are 0.533 {+-} 0.014 and 0.291 {+-} 0.042 respectively. The ratio of fractional independent yield of {sup 133m}Te to {sup 133g}Te was found to be R = 3.5 by using the measured fractional cumulative yields of {sup 133m}Te and {sup 133g}Te. From these results the initial fragment angular momentum of root-mean-square of {sup 133}Te has been deduced. The FCY of {sup 133m+g}Te determined in this work is in good agreement with the expectation value derived from Wahl`s system-atics of nuclear charge distribution in the fission. In the mass region of A 131{approx}141, there is no obvious effect of N = 82 neutron shell and proton pairing effects on the nuclear charge distribution.
