Cluster-Model Vertex Functions forO16: Backwardα-Particle Scattering

Abstract

We show by direct calculation that the heavy-particle-transfer model of backward elastic $\alpha$-particle scattering, together with the assumption of $\alpha$-cluster structure of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, is capable of explaining the large backward peak in elastic $\alpha$ scattering from ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$.
