A1 - Stock, Reinhard T1 - Shell-structure effect on elastic alpha scattering T2 - Physical review letters N2 - Back-angle enhancements of elastic alpha -scattering cross sections have been observed for nuclei at the ends of the 1p, 2s-1d, and f7 / 2 shells. Strong reduction of this enhancement occurs if excess neutrons enter the next open major shell. The results are discussed in terms of intermediate alpha structure.
