Measurement of cross sections for proton-induced reactions on natural Zn.

• A developed efficient analytical separation method of two radioisotopes, 67Cu and 67Ga. • The first data for natZn(p , x)67Cu reaction obtained by using the analytical separation method. • The present data being compared with those of the literature and the TENDL-2017 library. We present the cross sections for the nat Zn (p , x) 67 Cu and nat Zn (p , x) 67 Ga reactions within a proton energy range of 47.5–99.2 MeV. We efficiently separated the overlapping gamma-ray spectra of the two isotopes 67 Cu and 67 Ga , using an analytical method without radiochemical separation. The present data were compared with previous data from the literature, typically obtained by radiochemical separation before measuring the gamma-ray spectra of the two isotopes. Our results for the two isotopes generally showed greater or smaller values than those reported in the literature, except for some data concerning partial energy ranges, which were in agreement with the literature data. The present data were also compared with the TENDL-2017 library based on the TALYS code. [ABSTRACT FROM AUTHOR]
