Abstract

Elastic scattering and total reaction cross sections (via y ray yields) have been measured for 160+ 12C in the c.m. energy range 5· 5-10,0 MeV. Some well-defined structure is observed, with peak widths of order 250 keV. An optical potential which fits peaks in the total reaction cross section is shown to be inadequate to explain the elastic scattering data. Possible reasons for this inconsistency, which imply the need for a more general optical potential, are discussed.
