Proton induced reactions on natural Pb targets. A potential new cyclotron method for 201Tl production

Cross Sections for the 100 MeV Proton-Induced Nuclear Reactions and Yields of some Radionuclides Used in Nuclear Medicine

“…2 (a, b). The maximal cross sections for 52 Fe production were 1.3 mb (E p ~ 55 MeV) on 55 Mn and 0.36 mb (Ε, ~ 77 MeV) on 59 Co. They are in good agreement with the known data [15 -17].…”

“…The excitation functions of the reactions 55 Mn(p,4n) 52 Fe and 59 Co(p,2p6n) 52 Fe studied in this paper are shown in Fig. 2 (a, b).…”

“…The excitation function of this reaction was measured only once in the proton energy 73 -» 39 MeV range [15]. Another nuclear reaction from those listed in [14], 59 Co(p,2p6n) 52 Fe, was studied many years ago for the proton energies 98 59 MeV [16]. So, there are only pieces of information on the cross sections for the above reactions and more extensive re-investigations were desirable.…”

“…Among different cyclotron nuclear reactions yielding 52 Fe in interactions of charged particles with target nuclei [14] the 55 Mn(p,4n) 52 Fe reaction has the largest yield (0.67 mCi/μΑ-Ιι). The excitation function of this reaction was measured only once in the proton energy 73 -» 39 MeV range [15].…”

Proton-induced cross-sections of nuclear reactions on lead up to 37MeV

“…Lead is an important technological material as pure element as well as alloying agent and it is also widely used in different nuclear technologies, as well as target material for production of 201 Tl medical diagnostic gamma-emitter for SPECT technology (Lagunas-Solar et al, 1981). 205 Bi and 206 Bi have also medical interest, while they are used to study biokinetics of medically interesting 212,213 Bi alpha-emitter radioisotopes (Milenic et al, 2001).…”
