Yield measurements of alpha particles from the 27Al(p, α)24Mg and 31P(p, α)28Si reactions

Abstract

The yield of alpha particles from the 27Al(p, α)24Mg and 31P(p, α)28 reactions has been measured. Of the twelve known 27Al(p, γ)28Si resonances in the Ep = 500–850 keV region only those at Ep = 504, 631, and 728 keV gave a detectable alpha-particle yield. Upper limits are given for the yields at the other resonance levels. Of the five 31P(p, γ)32S resonance levels in EP = 400–850 keV region only that at EP = 641 keV shows detectable alpha-particle emission.
