Excitation functions of 124Te(p, xn)124,123I reactions from 6 to 31 MeV with special reference to the production of 124I at a small cyclotron

Proton induced reactions on natural tellurium up to 63 MeV: Data validation and investigation of possibility of 124I production

“…The curve is in good agreement with the data of Kiraly et al [10] in the early rising part. The data by Scholten et al [4] for the formation of 124 I via 124 Te( p, n) reaction in the energy range 5-15 MeV obtained using highly enriched 124 Te target agree with our data in that region after the data values by Scholten et al [4] were normalized to natural tellurium. Our excitation curve for 126 I differs considerably from the data of Acerbi et al [9] and Zweit et al [7], except for the energy region above 22 MeV for the former and below 20 MeV for the latter literature measurement.…”

“…7) the data by Acerbi et al [9] and Scholten et al [3] show good agreement with our data except in the early rising part (E p < 11 MeV). In the energy region below 20 MeV our data are not extensive but they agree more with the results of [4] and by Hohn et al [5] in the energy ranges 10-15, 26-45 and 55-65 MeV, respectively, obtained using highly enriched 120 Te and 122 Te targets agree with our data; but in the case of 125 Te target, our data are relatively higher and some deviation was observed from Hohn et al [5], especially in the energy range 55-60 MeV. All these comparisons were done after con- Table 3 and shown experimentally in Fig.…”

“…Extensive cross section measurements have been done at Jülich using highly enriched target materials, e.g. on 120 Te and 122 Te for production of 120g I [1,2], on 123 Te for production of 123 I [3], on 124 Te for production of 123 I and 124 I [4], and on 125 Te for production of 124 I [5]. As far as production via proton induced reactions on nat Te is concerned, excitation functions were reported by Zweit et al [6,7], Scholten et al [3], Kormali et al [8], Acerbi et al [9] and Kiraly et al [10] in the energy regions 7-60, 9-18, 6-18, 10-35 and 5-18 MeV, respectively, however, the available data are not enough for evaluation of all radioiodine isotopes.…”

New trends in nuclear data research for medical radionuclide production

“…The commonly used production method in each case is the low-energy ( p, n) reaction on the respective highly-enriched target nucleus. The basic data in all three cases were measured at the Forschungszentrum Jülich [40][41][42]. Although extensive development work related to targetry and chemical separation of those radionuclides has been done in many laboratories (for review cf.…”

Comparative studies on the production of the medically important radionuclide 124I via p-, d-, 3He- and α-particle induced reactions

“…It is generally produced using the 124 Te(p,n) 124 I [1] or 124 Te(d,2n) 124 I [2] reaction at low energies. However, other possible production routes deserved detailed investigations to find a high yield, high purity route.…”
