We measured the excitation functions for the production of the radionuclides \(^{{95}}\hbox {Zr}\), \(^{95\mathrm {m}}\hbox {Nb}\) and \(^{95\mathrm {g}}\hbox {Nb}\) from the \(^{\mathrm {nat}}\hbox {Zr}(\hbox {p},\hbox {x})\) reactions in the proton energy range of 10.6–43.6 MeV. The experiment was performed by irradiation of zirconium and copper foils simultaneously using 45 MeV proton beam from the MC-50 Cyclotron at the Korea Institute of Radiological and Medical Sciences, Korea, and the induced activity was measured with an HPGe \(\upgamma \)-ray detector. Proton energies along the foil stack were calculated using the computer code SRIM-2013. The proton beam flux entered each foil was determined via the \(^{\mathrm {nat}}\hbox {Cu}(\hbox {p},\hbox {x})^{{62}}\hbox {Zn}\) and \(^{\mathrm {nat}}\hbox {Cu}(\hbox {p},\hbox {x})^{{65}}\hbox {Zn}\) monitoring reactions. The cumulative cross sections of the \(^{\mathrm {nat}}\hbox {Zr}(\hbox {p},\hbox {x})^{{95}}\hbox {Zr}\) reaction were measured because it was unable to separate the activity from the decay of \(^{{95}}\hbox {Y}\) to \(^{{95}}\hbox {Zr}\). However, independent cross sections of the \(^{\mathrm {nat}}\hbox {Zr}(\hbox {p},\hbox {x})^{95\mathrm {m}}\hbox {Nb}\) and \(^{\mathrm {nat}}\hbox {Zr}(\hbox {p},\hbox {x})^{95\mathrm {g}}\hbox {Nb}\) reactions were determined, since the independent activities of \(^{95\mathrm {m}}\hbox {Nb}\) and \(^{95\mathrm {g}}\hbox {Nb}\) can also be measured. In addition, the thick target yields of the \(^{{95}}\hbox {Zr}\), \(^{95\mathrm {m}}\hbox {Nb}\) and \(^{95\mathrm {g}}\hbox {Nb}\) isotopes were also determined. The current results are compared with the previously measured data as well as with the theoretical values from the TALYS-1.9 code and the TENDL-2019 data library.
