On-Line Studies of Mass-Separated Xenon Fission Products

Abstract

Mass-separated, short-lived Xe fission products from ${\mathrm{Cf}}^{252}$ have been studied using on-line nuclear spectroscopy. The Xe isotopes from a 10-\ensuremath{\mu}g Cf source were separated in the Princeton Isotope Separator, and the decay properties of the separated isotopes were measured with a Ge(Li) detector located at the collector of the separator. Results from measurements of the decay of ${\mathrm{Xe}}^{137\ensuremath{-}142}$ and accompanying Cs and Ba isotopes are discussed.
