($p, n$) Cross Sections on ${\mathrm{Ti}}^{47}$, ${\mathrm{V}}^{51}$, ${\mathrm{Cr}}^{52}$, ${\mathrm{Co}}^{59}$, and ${\mathrm{Cu}}^{63}$ from 4 to 6.5 Mev

Absolute ($p, n$) cross sections have been measured for ${\mathrm{Ti}}^{47}$, ${\mathrm{V}}^{51}$, ${\mathrm{Cr}}^{52}$, ${\mathrm{Co}}^{59}$, and ${\mathrm{Cu}}^{63}$ at energies between 4 and 6.5 Mev. These data plus earlier measurements of the cross section for inelastic proton scattering have been used to estimate total proton absorption cross sections for ${\mathrm{V}}^{51}$ and ${\mathrm{Co}}^{59}$. An optical model calculation using parameters giving a good fit to elastic scattering measurements predicts an absorption cross section in good agreement with the measurements for ${\mathrm{Co}}^{59}$. For ${\mathrm{V}}^{51}$, some sets of parameters gave good agreement with the measured absorption cross section, but the fit to the elastic scattering data was only fair.
