We measured the excitation functions for the production of the radionuclides 
, and from the 
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 
-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 
and 
monitoring reactions. The cumulative cross sections of the reaction were measured because it was unable to separate the activity from the decay of 
to . However, independent cross sections of the 
and 
reactions were determined, since the independent activities of and can also be measured. In addition, the thick target yields of the , and 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.
