Excitation functions of (p,γ) and (p,n) reactions on zinc up to 4 MeV

Proton-induced reaction cross sections for 64 Zn( p,γ ) 65 Ga, 67 Zn( p,γ ) 68 Ga, 70 Zn( p,n ) 70 Ga, and nat Zn( p,x ) 67 Ga were measured in the 2.0–4.0 MeV energy range at a 3 MV Tandem Accelerator, using the stacked-foil activation technique in combination with high resolution γ -ray spectrometry. The obtained results are comparable to literature data determined via prompt γ -counting and X-ray counting methods. The excitation functions of this work are reproduced well by a model calculation using the code TALYS with a few chosen input parameters. The data should be useful in astrophysical research as well as in production of radionuclides at a small medical cyclotron.
