Analysis of the Elastic Scattering of Protons fromF19

Abstract

An analysis of the anomalies in the elastic scattering cross section of protons on ${\mathrm{F}}^{19}$ has been carried out. The assignments ${1}^{+}$ for the resonances at 669, 935, and 1422 kev, and ${0}^{+}$ for the resonance at 843 kev, are required by the results of the experiment. The assignment of the resonances at 873, 1348, and 1374 kev is ${2}^{\ensuremath{-}}$, with ${1}^{\ensuremath{-}}$ not excluded by these data alone. Unique values of the partial widths are determined for these resonances and several others in this energy range. Reduced widths are given for the various particle reactions which are observed.
