Thallium-201 yields and excitation functions for the lead radioactivities produced by irradiation of thallium-205 with 34–60 MeV protons

Equilibrium and pre-equilibrium emissions in proton-induced reactions on 203,205Tl

“…Therefore, we have given only theoretical calculations in figure 1. The calculation for the excitation function of 205 Tl(p, 3n) 203 Pb reaction is compared with the reported experimental values in figure 5 [17]. The pre-equilibrium calculations (hybrid and GDH models) and cascade-exciton model calculations are in good agreement with the experimental data.…”

Excitation Functions for the Formation of 200,201,202Pb by Proton Induced Nuclear Reactions on Enriched 204Pb

“…Most commercial suppliers of 201 T1 use low energy reactions 203 Tl(p,3n) 201 Pb 201 T1 (E p < 30 MeV) on expensive, isotopically enriched (>95%) 203 T1 targets [3,7]. The 205 Tl(p,5n) 201 Pb 201 T1 reaction, on the other hand, is the basis for an alternative 201 T1 production method limited to high energy (E p > 45 MeV) research accelerators [3,6]. Both reactions can be used in the development of a 201 T1 production using double targets.…”

“…Thallium 201 can be produced in a carrier-free form either indirectly via the decay of its precursor 9.4 h 201 Pb [3][4][5][6][7][8] or directly by irradiating Hg with protons or deuterons [8,9]. Most commercial suppliers of 201 T1 use low energy reactions 203 Tl(p,3n) 201 Pb 201 T1 (E p < 30 MeV) on expensive, isotopically enriched (>95%) 203 T1 targets [3,7].…”

Investigation of activation cross-sections of proton induced nuclear reactions on natTl up to 42MeV: Review, new data and evaluation

“…The 201 T l can be produced at charged particle accelerators. The investigated nuclear reactions are collected in Table. 1 (Adam-Rebeles et al, 2012;AlSaleh et al, 2007;Bell and Skarsgard, 1956;Birattari et al, 1982;Blue et al, 1978;Comar and Crouzel, 1975;Dmitriev et al, 1976;Fernandes and da Silva, 1992;Gloris et al, 2001;Hermanne et al, 1992;Kuhnhenn et al, 2001;Lagunas-Solar et al, 1980, 1981Lebowitz et al, 1975;Nayak et al, 2002;Qaim et al, 1979;Sakai et al, 1965;Zaitseva et al, 1987).
