Elastic Scattering of Deuterons byO16

Abstract

Thin targets of silicon dioxide on Formvar were bombarded with deuterons in order to study the yield of deuterons elastically scattered from ${\mathrm{O}}^{16}$. The incident deuteron energy was varied in approximately 20-kev steps from 4.6 to 7.2 Mev for observations at 130 degrees, and from 4.6 to 7.0 Mev for observations at 90 degrees. The absolute cross section was determined by comparisons with the known ${\mathrm{O}}^{16}$ elastic proton cross section. The yield shows resonant structure; in particular, at least eight maxima occur at 130 degrees, and five of these appear at 90 degrees. The resonances are not isolated but indicate overlapping levels.
