Investigation of the production of 68Ga using pre-equilibrium models

•Some probable nuclear reactions for production of 68Ga radioisotope are investigated.•The pre-equilibrium models are used.•The excitation functions and emission spectra are investigated.•The best reaction to produce 68Ga for using in the PET process is suggested.

In this study, some nuclear reactions for the production of 68Ga radioisotope are investigated using pre-equilibrium nuclear reaction models. For this aim, by the pre-equilibrium reaction mechanisms, the excitation functions and emission spectra of some nuclear reactions for the production of 68Ga radioisotope are calculated. These calculations are performed in the ALICE/ASH and the TALYS 1.6 codes. The obtained results have been discussed and compared with the available experimental results.
