FINE STRUCTURE IN THE O16(γ, n)O15 YIELD CURVE

Abstract

Fine structure in the O^I6(γ, n)O¹⁵ yield curve near threshold was examined using improved experimental techniques. Breaks were observed at threshold, 15.85, 16.14, 16.45, 16.74, 16.88, 17.05, 17.15, and 17.21 Mev. These energies are established to within ± 0.04 Mev. The integrated photon absorption cross section in these breaks resulting in (γ, n) reactions was found to be 0.47 ± 0.11 Mev-mb. Our results are in good agreement with the measurements of other workers.
