The method of choice for routine production of {sup 67}Ga on a low energy cyclotron is the {sup 67}Zn(p,n){sup 67}Ga reaction while above 20 MeV the {sup 68}Zn(p,2n){sup 67}Ga process results in a higher yield of gallium. To optimize the yields in a production setting it is important to know the cross sections/thick target yield data of these reactions. In spite of the large amount of experimental information on cross section/thick target yield data of the desired reactions published up to 1993, the status in some cases is not satisfactory. In the present work, the authors have compared the available cross sections/thick target yield data and have tried to resolve the most obvious discrepancies which have appeared in the literature. The authors also present an evaluated data base for the mentioned data for the {sup 67}Zn(p,n){sup 67}Ga and {sup 68}Zn(p,2n){sup 67}Ga nuclear reactions.
