Cross section studies on 64Cu with zinc target in the proton energy range from 141 down to 31 MeV

Investigation of the 68Zn(p, 2p)67Cu nuclear reaction: New measurements up to 40 MeV and compilation up to 100 MeV

“…All authors used highly enriched 68 Zn targets, except Bonardi et al . [2] who irradiated natural zinc samples. In all cases the 67 Cu activity was measured after high-efficiency chemical separation of 67 Cu from the irradiated zinc targets.…”

“…Recently Bonardi et al [2] have investigated the nat Zn(p, x) 67 Cu process from 31 to 141 MeV. (Eight data points are available below 100 MeV).…”

“…Fortunately, in the investigated energy region the contribution of the 70 Zn(p, a) reaction to the natural values is practically negligible due to (1) the low natural isotopic abundance of 70 Zn in natural zinc (0.7%) and (2) the magnitude of this reaction based on the results of Levkovskij [4] and Kastleiner et al [8]). Thus the results of Bonardi et al [2] can be used for a database, simply multiplying their natural values with 100/18.8. Unfortunately, Bonardi et al [2] reported their results only in a figure, therefore the use of their results for a data base is possible only with the introduction of an additional, non-systematic uncertainty both in proton energy scale and cross-section values.…”

“…Excitation functions of the 68 Zn(p, 2p) and the 70 Zn(p, a) nuclear processes, forming the above radioisotope, have been investigated by several groups below 100 MeV (for the (p, 2p) reaction: Bonardi et al [2], Cohen et al [3], Levkovskii [4], McGee et al . [5], Morrison and Caretto [6] and Stoll et al [7]; for the (p, a) reaction: Levkovskij [4] and Kastleiner et al [8]).…”

Experimental and calculated nuclear reaction data relevant to innovative production of medical radioisotopes

“…For the other radionuclides, main care has been devoted by the authors to critically survey the relevant results, as from the published papers [3][4][5][6][7].…”
