Independent formation cross sections in the fission of 238U by protons of energy 20–85 MeV were obtained for the nuclides 111Ag, 112Ag, 117In, 115In, 111Pd, and 115Cd. The last three mentioned were estimated on the basis of measurements and isomeric yield data. Charge dispersion curves were constructed and Zp, the most probable charge, determined. The values for (ZA − Zp) lie intermediate between those measured for fission products of higher and lower mass. The number of neutrons emitted was estimated and found to be higher than in asymmetric fission, leading to the conclusion that the former are events arising from higher deposition energies.

Uniform Charge Distribution

A model of nuclear shape oscillations is set up for an arbitrary nuclear charge distribution. For a uniform charge distribution the model reduces to the liquid drop model. The model is used to consider ?-transitions and electron excitation of nuclei. Explicit expressions are obtained for four charge distributions: (a) uniform, (b) Gaussian, (c) exponential, (d) uniform with Gaussian "edge". The theory predicts a relative angular distribution of electrons scattered by the 4�43 MeV level of 12C in agreement with the experimental results of Fregeau and Hofstadter (1955), but gives a scattered intensity seven times too large.
