Excitation functions for proton nuclear reactions on 64Zn, 66Zn, and 68Zn by stacked foil method

The excitation functions of the (p, n), the (p, alpha), and the (p, pn) reactions on 64 Zn, 66Zn, and 68Zn were measured with the stacked foil method and the high-purity Ge (HPGe) semiconductor detector at proton energies from 3 to 18 MeV. We accelerated protons with a proton accelerator of cyclotron type and connected a current integrator with a Faraday cup to measure the flux of proton beam. The incident proton energies were evaluated on each stacked foil by using the semi-experimental stopping power formula. The experimental results were compared with other experimental data and most of them are taken from the experimental nuclear reaction database (EXFOR).
