Stripping of two protons and one- alpha -particle transfer reactions for 16O+ASm and their influence on the fusion cross section.

Abstract

Transfer cross section angular distribution data for the stripping of two protons and one \ensuremath{\alpha} particle are studied for the $^{16}\mathrm{O}$${+}^{\mathit{A}}$Sm systems (A=144, 148, 150, 152, and 154), at near barrier energies. A semiclassical formalism is used to derive the corresponding transfer form factors. The influence of short distance transfer reactions on the fusion is discussed. \textcopyright{} 1996 The American Physical Society.
