Cross sections for 34 proton-induced nuclear reactions on isotopically enriched molybdenum (${}^{92,94-98,100}\mathrm{Mo}$) leading to production of ${}^{92}\mathrm{Tc}$, ${}^{93\mathrm{m}}\mathrm{Tc}$, ${}^{93\mathrm{g}}\mathrm{Tc}$, ${}^{94\mathrm{m}}\mathrm{Tc}$, ${}^{94\mathrm{g}}\mathrm{Tc}$, ${}^{95\mathrm{m}}\mathrm{Tc}$, ${}^{95\mathrm{g}}\mathrm{Tc}$, ${}^{96\mathrm{m}+\mathrm{g}}\mathrm{Tc}$, ${}^{97\mathrm{m}}\mathrm{Tc}$, ${}^{99\mathrm{m}}\mathrm{Tc}$, ${}^{101}\mathrm{Tc}$, ${}^{91(\mathrm{m}+\mathrm{g})}\mathrm{Mo}$, ${}^{93\mathrm{m}}\mathrm{Mo}$, ${}^{99}\mathrm{Mo}$, ${}^{89\mathrm{m}}\mathrm{Nb}$, ${}^{89\mathrm{g}}\mathrm{Nb}$, ${}^{91\mathrm{m}}\mathrm{Nb}$, ${}^{92\mathrm{m}}\mathrm{Nb}$, ${}^{95\mathrm{m}}\mathrm{Nb}$, ${}^{95\mathrm{g}}\mathrm{Nb}$, ${}^{96}\mathrm{Nb}$, and ${}^{97\mathrm{m}+\mathrm{g}}\mathrm{Nb}$ were measured in the energy range 8–19 MeV with the activation method using individual irradiations. The experimental data were compared with published data from natural abundance and isotopically enriched targets as well as with the predictions of the nuclear reaction code talys. Special attention was given to the medically relevant ${}^{100}\mathrm{Mo}$($p,2n$)${}^{\mathrm{99m}}\mathrm{Tc}$ and ${}^{100}\mathrm{Mo}$($p,pn$)${}^{99}\mathrm{Mo}$ as well as nine reaction cross sections that had not previously been measured in this energy range.
