KINETIC ENERGY AND MASS DISTRIBUTIONS FOR NUCLEAR FISSION AT MODERATE EXCITATION ENERGY

摘要

The data were then transformed into maces - total kinetic energy maps and analyzed by means of moments. The 3i and Au data are in good agreement with quantitative theoretical predictions from the liquid drop model available for the lighter elements. The U and Th data are discussed in terms of qualitative ideas which have been propose to explain the properties of the fission process for the heavier elements. The changes in the U and Th mass and total kinetic energy distributions with excitation energy are emphasized. Pulse-highs energy relations for the detectors used were obtained by a detailed comparison of detector and time-of-flight results for the spontaneous fission of Cf252.
