Abstract

The 20-30 MeV excitation energy region of ${}^{16}O$ was investigated by inelastic scattering of 45 MeV protons and 60 MeV $α$ particles. Both $E 1$ and $E 2$ strengths are present, exhausting, respectively, about 50% and between 16 and 21% of the corresponding energy-weighted sum rule. Microscopic calculations also reproduce angular distributions fairly well.
