Title: TOTAL NEUTRON CROSS SECTION OF XENON AND KRYPTON

Abstract

By the thermal diffusion method, using 12 meters of hot-wire columns, concentrations of the xenon isotopes In good quantity (about 5700 Xe/sup 129/ In the light fraction and 27% Xe/sup 136/ in the heavy one) were produced without recycling. A fair-sized sample of "light" krypton, analyzing better than 50% Kr/ sup 80/, was available from earlier thermal diffusion separation with recycling by Blais and Watson. These samples together with the normal gases were concentrated to thicknesses of about 3.3 g/cmin special gas target holders for use with the Brookhaven fast chopper. For krypton, neutron widths and isotopic identifications were determined for the following levels: 27.9 ev in Kr/sup 83/, 39.8 ev In Kr/sup 82/, 106 ev in Kr/sup 80, 233 ev in Kr/sup 83/ 519 ev in Kr, 580 ev in Kr, and 640 ev in either Kr/sup 78/ or Kr/sup 80/. Total widths and radiation widths were obtained for the 27.9- and 106-ev levels by thick-thin area analysis. For xenon, new resonances are observed at 5.2 ev In Xe/sup 124/, 9.5 ev in Xe/sup 129/, 14.1, 46.0, and 76.0 ev all in Xe/sup 131/, 92.0 ev in Xe/sup 129/, and 126 ev to be assigned to either the 128,more » 129, or 130 isotope.
