Deuteron Stripping by Heavy Nuclei

Theoretical angular distributions for the proton groups following bombardment of ${\mathrm{Pb}}^{206}$ and ${\mathrm{Bi}}^{209}$ by deuterons with energies less than 10 Mev are compared with experimental measurements of Stokes. Both theoretical and experimental angular distributions show peaking in the backwards direction, characteristic where Coulomb effects dominate the stripping. The theoretical curves fall off faster than the experimentally measured distributions, which show a tendency to level off in the region $\Theta >140\mathrm{}°$. The insensitiveness of the stripping integral to the value of the cutoff radius parameter is demonstrated by numerical calculations.
