FISSION PRODUCT CHAIN YIELDS FROM ISOTOPE ABUNDANCE MEASUREMENTS

Abstract

A 90° sector type mass spectrometer utilizing a heated relative abundances and yields of fission production isotopes of Cesium and Rubidium. The minimum sample require* meats for analysis of alkali metals Is of the order of .1 micrograms whereas at least 5 micrograms are necessary for alkaline earths such as Ba and Sr. Isotopic abundances are reported for stable Ba, Sr, 11, K, and Rb»
