HEAVY MASS YIELDS IN THE SLOW NEUTRON FISSION OF U$sup 23$$sup 3$
Technical Report

OSTI ID:4108188
The chain yields of masses 157, 159, and 161 in the thermal neutron fission of U/sup 233/ were determined by radiochemical methods. The last radioactive member of the mass chain was isolated, and its activity was measured relative to Mo/sup 99/. With this ratio and pertinent data from the thermal neutron fission of U/sup 235/, the mass chain yield was calculated. The chain yields are higher than was to be expected from analogy with the relative yields from thermal neutron fission of U/sup 235/ and U/sup 239/. A possible explanation is given. The chain yields of masses 91, 141, 143, 144, U/sup 233/ and U/sup 235/ were also determined in the same manner. The values, when compared to the literature values for the chain yields, provided an estimate of the accuracy of the radiochemical measurement. The accuracy is estimated to be plus or minus 10%. A new value was calculated for the chain yield of mass-157 in the thermal neutron fission of U/sup 235/. An improved value was obtained for the chain yield of mass156 in the thermal neutron fission of U/sup 233/. (auth)
