Excitation functions and thick target yields of the natZr(p,x)95Zr , 95mNb , 95gNb reactions

We measured the excitation functions for the production of the radionuclides 9⁵Zr , 95^mNb and 95^gNb from the na^tZr(p,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 γ -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 na^tCu(p,x)⁶²Zn and na^tCu(p,x)⁶⁵Zn monitoring reactions. The cumulative cross sections of the na^tZr(p,x)⁹⁵Zr reaction were measured because it was unable to separate the activity from the decay of 9⁵Y to 9⁵Zr . However, independent cross sections of the na^tZr(p,x)^{95 m}Nb and na^tZr(p,x)^{95 g}Nb reactions were determined, since the independent activities of 95^mNb and 95^gNb can also be measured. In addition, the thick target yields of the 9⁵Zr , 95^mNb and 95^gNb 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.
