Proton Inelastic Scattering fromCa48

Inelastic proton scattering from ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$ has been measured at beam energies 25, 30, 35, and 40 MeV. Angular distributions from 13 to 97° for 22 inelastic states were obtained. Analyses with the collective distorted-wave Born approximation are presented. A direct comparison of the excitation of the ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$ 3.830-MeV $2^{+}$ and 6.342-MeV $4^{+}$ states is made with the low-lying excited $2^{+}$ and $4^{+}$ states of ${}_{}{}^{50}{}_{}{}^{}\mathrm{Ti}$ and ${}_{}{}^{52}{}_{}{}^{}\mathrm{Co}$.
