Compilation of cross sections/thick target yields for 66Ga, 67Ga and 68Ga production using Zn targets up to 30 MeV proton energy

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

“…Unfortunately, a significantly higher amount of 67 Ga than 67 Cu is formed in any energy region up to 100 MeV [c.f. 13,14]. The above fact and the close-lying half-lives of 67 Cu (T 1/2 = 61.9 h [1]) and 67 Ga (T 1/2 = 78.3 h [1]) also motivated the use of chemical separation before the gamma spectroscopy.…”

“…Their results show the 'lowest' excitation function curve (based on eight measured cross-sections up to 85 MeV). As it was already shown elsewhere [14] the cross-sections of McGee et al [5] should be re-normalized due to the recently corrected values of the copper monitor reactions that was used in the original work. The new monitor data can be found in [15].…”

Development of novel positron emitters for medical applications: nuclear and radiochemical aspects

“…4 [32]. The major radioactive products formed are 73 Se, 74 As and 65 Zn through the nuclear reactions 75 As( p, 3n) 73 Se, 75 As( p, pn) 74 As and 65 Cu( p, n) 65 Zn, respectively. The removal of [ 74 As]As 2 O 3 is carried out at about 660 • C and that of radioselenium at about 1100 • C, while 65 Zn remains in the quartz tube within the oven area.…”

“…For example, the intermediate energy deuterons could be useful in the production of 64 Cu via the nat Zn(d, x)-process [100,101] and 73 Se via the 75 As(d, 4n)-reaction [102]. Similarly, 75 Br and 76 Br are still produced via the 75 As( 3 He, 3n) 75 Br and 75 As( 3 He, 2n) 76 Br reactions, respectively, because of the difficulty in target construction while using enriched 76 Se.…”

“…Removal of radioselenium at 900-1100 • C to zone (a). The activity profile was determined using the 361 keV γ -ray of 73 Se. The volatalized 65 ZnO remains in the quartz tube within the oven area.…”
