Experiment on O¹⁸(p, γ)F¹⁹ Reaction

Abstract

Oxygen 18 was bombarded with protons having energies over a range from 570 keV to 1500 keV, and proton capture gamma rays were studied. Four resonance levels were observed at proton energies 628, 847, 1167, and 1397 keV, and their widths were estimated to be 2.7, 44, 0.6 and 3.7 keV, respectively. From an analysis of angular distributions of gamma rays emitted from the resonance level at E_p=1167 keV, it was deduced that spin values of the 9.07–, 2.78–, and 1.35–MeV levels of F¹⁹ were 7/2, 9/2, and 5/2, respectively. The results were compared with the theoretical predictions based on shell model and collective model calculations.
