Protons from the 90-in. cyclotron at Lawrence Radiation Laboratory (LRL)-Livermore have been scattered from enriched targets of $^{70,72,74,76}\mathrm{Ge}$, with an over-all energy resolution (FWHM) of 70 keV. The incident proton energy was approximately 14.5 MeV, and angular distributions were obtained from 20\ifmmode^\circ\else\textdegree\fi{} to 150\ifmmode^\circ\else\textdegree\fi{}, in 10\ifmmode^\circ\else\textdegree\fi{} intervals. The elastic-scattering results were analyzed using the optical model. Angular distributions were obtained for inelastic proton groups from seven levels in $^{70}\mathrm{Ge}$, nine levels in $^{72}\mathrm{Ge}$, eleven levels in $^{74}\mathrm{Ge}$, and ten levels in $^{76}\mathrm{Ge}$---all below 3.5-MeV excitation. These included scattering to the quadrupole and octupole one-phonon vibrational levels and scattering to the ${0}^{+}$, ${2}^{+}$, ${4}^{+}$ two-quadrupole-phonon triplet. The data were analyzed using a coupled-channel computer code and a vibrational model of the nucleus. Strengths to excited states (${\ensuremath{\beta}}_{I}$) and spins and parities of levels were determined and are compared with Coulomb-excitation decay studies and with other scattering experiments.
