Abstract
Backward-angle excitation functions () have been measured for the systems + and + for elastic and inelastic scattering to the first excited state in . Over the investigated energy range, MeV, the elastic and inelastic data exhibit gross structure resonances of widths between 1 and 2 MeV modulated by a finer structure for + ( keV). Shape resonances with different principal quantum numbers are suggested as an explanation of the resonances.
