Macklin, R. L.

Evidence for neutron capture in /sup 134/Xe at 2154-eV and 18.4-keV resonances is presented and quantified in terms of limits on Breit-Wigner single level parameters. Assuming the radiation width, 32 meV, found at the 18.4-keV resonance for all the reported resonances at higher energies, the Maxwellian average capture cross section is calculated for a range of stellar interior temperatures T. For kT = 30 keV only 0.72 mb is found. Only one third of this comes from the resonances above 18.4 keV so an overall uncertainty at kT = 30 keV of /+-/0.11 mb at the 68% probability level seems reasonable. Four resonances in /sup 134/Xe were also found. 11 refs., 5 figs.
