Fission Yields of Cesium, Rubidium, and Strontium Isotopes and Their Relation to Fine Structure in Fission

Abstract

The various concepts of the fission process, mass and charge distribution, and fine structure in fission yields are reviewed. Details and results of mass spectrometric analyses of fission-product samples of cesium, rubidium, and strontium are reported. Absolute yield values have been assigned to the mass 87, 135, and 137 chains. Relative yields of the mass 88 and 90 chains have been determined. A mechanism is postulated to account tor anomalies in fission fine structure. The Glendenin mechanism of instantaneous neutron emission is found to require modification.
