A ${}_{}{}^{92}{}_{}{}^{}\mathrm{Mo}$ beam with an energy of E/A=70 MeV has been used to produce new isotopes near the proton drip line. The Michigan State University National Superconducting Cyclotron Laboratory A1200 fragment separator was used to detect the new isotopes ${}_{}{}^{78}{}_{}{}^{}\mathrm{Y}$, ${}_{}{}^{82}{}_{}{}^{}\mathrm{Nb}$, ${}_{}{}^{85}{}_{}{}^{}\mathrm{Mo}$, ${}_{}{}^{86}{}_{}{}^{}\mathrm{Tc}$, and ${}_{}{}^{89,90}{}_{}{}^{}\mathrm{Ru}$.
