Abstract
The production cross section of the medical isotope 68Ga in the 68Zn(p,n)68Ga reaction was measured with the proton energies of 8.6 ± 0.9, 12.1 ± 0.5, 15.1 ± 0.3 and 17.7 ± 0.2 MeV by using the method of stacked-foil activation and off-line γ-ray spectrometry. The proton beam intensity at the front position of each natZn was determined by using the natCu(p,x)62Zn monitor reaction with the recommended cross section from the IAEA data base library. The 68Zn(p,n)68Ga reaction cross-section as a function of proton energy was theoretically calculated by using the default parameters of the computer code TALYS 1.9 and are found to be in general agreement with the present results.
