Proton and deuteron activation measurements at the NPI and future plans in SPIRAL2/NFS

Abstract

Abstract. The proton-and deuteron-induced reactions are of a great interest for the assessment of induced radioactivity of accelerator components, target and beam stoppers as well as isotope production for medicine. In the present work, the deuteron-induced reaction cross sections on zinc were investigated by stacked-foil activation technique with deuteron beam of 20 MeV energy from the cyclotron U-120M of NPI CASŘež. Also the proton activation cross section measurement of iron is presented. The comparison of present results to data of other authors and to predictions of evaluated data libraries is discussed. The investigation shall continue for higher proton and deuteron energy interval 20-35 MeV at SPIRAL2/NFS facility using a charged particle irradiation chamber with pneumatic transport system to measure isotopes and isomers with half-lives in minutes-regions.

Production cross sections of 68Ga and radioactive by-products in deuteron-induced reactions on natural zinc

“…The measured excitation function is shown in Fig. 2 in comparison with the previous experimental data on nat Zn (Nassiff and Münzel, 1972;Šimečková et al, 2017) and 68 Zn (Gilly et al, 1963) and the TENDL-2017 data (Koning et al, 2019). Our result is consistent with the recent data reported by Šimečková et al (2017) but inconsistent with the data by Nassiff and Münzel (1972) in the whole energy region.…”

“…The present result is shown in Fig. 4 with the experimental data studied earlier on nat Zn (Bonardi et al, 2003;Fateh et al, 1996;Khandaker et al, 2015;Nassiff and Münzel, 1972;Šimečková et al, 2017;Tárkányi et al, 2004) and 66 Zn (Bissem et al, 1980;Gilly et al, 1963;Steyn and Meyer, 1973;Vlasov et al, 1957;Williams and Irvine, 1963) and the TENDL-2017 data (Koning et al, 2019).…”

“…The measured excitation function is shown in Fig. 5 together with the previous experimental data on 64 Zn (Bissem et al, 1980;Coetzee and Peisach, 1972;Morrison and Porile, 1959) and on nat Zn (Nassiff and Münzel, 1972;Šimečková et al, 2017) and the TENDL-2017 data (Koning et al, 2019). Our data have a larger uncertainty than the others due to the relative uncertainty of the intensity (24%) of the 115.09-keV γ-line (International Atomic Energy Agency, 2009).…”

“…The measured excitation function is shown in Fig. 6 in comparison with the previous experimental data on 68 Zn (Baron and Cohen, 1963;Gilly et al, 1963), on nat Zn (Bonardi et al, 2003;Khandaker et al, 2015;Nassiff and Münzel, 1972;Šimečková et al, 2017;Tárkányi et al, 2004), and the TENDL-2017 data (Koning et al, 2019).…”

“…The deuteron-induced reactions on zinc are another candidate route for the 68 Ga production because the cross sections of the deuteron-induced reactions on zinc isotopes are comparable with those of the proton-induced ones according to the TENDL-2017 library (Koning et al, 2019). A few experimental cross section data of the nat Zn(d,x) 68 Ga reaction (Nassiff and Münzel, 1973;Šimečková et al, 2017) and the 68 Zn(d,2n) 68 Ga reaction (Gilly et al, 1963) were reported in the literature. From the comparison of these results, however, a notable discrepancy among them is seen.…”
