Angular Correlation Between α-Particles and γ-Rays in the Reaction F^(19)(p,αγ)O^(16)

Abstract

We have studied the correlation between the directions of emission of alpha-particles and gamma-rays at the 340-keV. resonance in the following reaction:F^(19) + p → Ne^(20*) → O^(16*) + y + ɑ. Both alpha-particles and gamma-rays were observed in the plane perpendicular to the proton beam. The alpha-particles were detected in a proportional counter with a window sufficiently thick (approximately 6.5 mm. air equivalent) to exclude protons scattered from the calcium fluoride target. The 6.1-MeV. gamma-rays emitted from the oxygen-16* nuclei were detected in a lead-walled Geiger counter. Coincidences between the alpha-particles and the gamma-rays were measured as a function of angle between the counters.
