Charge distribution in the spontaneous fission of {sup 252}Cf. Determination of cumulative yields of {sup 127g}Sn and {sup 128}Sn

Technical Report:

Abstract

The cumulative yields (CY) of {sup 127g}Sn and {sup 128}Sn in the spontaneous fission of {sup 252}Cf have been determined by the radiochemical method. The values are (0.0437 {+-} 0.0021)% and (0.145 {+-} 0.007)% respectively. The cumulative yield of {sup 128}Sn determined in this work is lower than the expectation value (0.164%) obtained by the empirical Z{sub p} model but in good agreement with the expectation value (0.145%) according to empirical A{sub p}{sup `} model. Both the yield of {sup 128}Sn measrued and the yields of Tc and In measured in the thermal neutron-induced fission of {sup 235}U have shown that the empirical A{sub p}{sup `} model is better than Z{sub p} model in representing nuclear charge distribution near the symmetrical range in fission.
