Interpretation of theH3(p, n)Reaction

Abstract

The angular and energy dependence of the ${\mathrm{H}}^3(p, n)$ reaction at energies up to a few Mev have been much analyzed for their possible indication of resonances in the "compound nucleus" ${\mathrm{He}}^4$. It is shown that the experimental data can be explained on the basis of "direct" interactions, without assuming that any compound-nucleus state is involved. A combination of "knock-on" and "pickup" effects is involved.
