High-resolution study ofCa40via inelastic proton scattering at 35 MeV

Spectra of inelastic proton scattering on ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ have been obtained with 4.5 keV resolution at a bombarding energy of 35 MeV. Cross sections for the excitation of several previously unresolved particle-hole states have been measured. Nearly all known energy levels plus nine new levels have been observed up to an excitation energy of 9.3 MeV, slightly above the proton separation energy, and accurate excitation energies have been determined for these states.
