“…The microscopic experimental cross-section data on monoisotopic niobium can also be very useful for verification of nuclear reaction theory. We have already reported results on production of 93m Mo up to 10 MeV deuteron energy [13], 40 MeV deuteron energy [14] and 43 MeV alphas [15], earlier results of other authors on Nb + p were also found in the literature. We had also earlier systematic investigations on the excitation functions for production of 88 Zr and 88 Y (due to their medical and biological importance [16][17][18]) by proton and deuteron irradiation of Mo, Nb, Zr and Y targets [19], but the data for high energy proton irradiation on Nb is not complete and not reliable yet.…”

“…Keeping in mind the importance of proton rich radionuclides of Tc, we have investigated heavy ion induced production route of 93,94,95 Tc by bombarding 9 Be on natural yttrium target. Attempt has been made to develop different radiochemical separation technique for isolation of nca Tc from the bulk target matrix.…”

9 Be induced nuclear reaction / Stacked-foil technique / Proton rich / 93,94,95 Tc / Production yield / Liquid-liquid extraction / Solid-liquid extraction Summary. Proton rich Tc radionuclides have been produced for the first time through 89 Y( 9 Be, xn) 93,94,95 Tc reactions. In order to optimize the yield of a particular radionuclide of choice, batch yield of 93 Tc, 94 Tc and 95 Tc have been measured at different incident energies using stacked-foil technique followed by off-line γ -spectrometry. No-carrier-added (nca) 93,94,95 Tc radionuclides have been separated from bulk yttrium by liquid-liquid extraction (LLX) and solid-liquid extraction (SLX) techniques. Trioctylamine (TOA) diluted in cyclohexane was used as liquid anion exchanger in LLX in presence of HCl. SLX was carried out using cation and anion exchanger resin, DOWEX-50 and DOWEX-1, respectively, in HCl medium.

“…New experiments were performed on Ti and Cu targets stacked together and the nat Ti(α,x) 51 Cr, nat Cu(α,x) 66 Ga, nat Cu(α,x) 67 Ga and nat Cu(α,x) 65 Zn reactions were cross checked. Additional data were found which were measured on copper and used as monitor reactions in other independents experiments [6][7][8], therefore only the shape information of the excitation functions was used in the evaluation process. In the light of these new results the recommended cross sections for nat Ti(α,x) 51 Cr, nat Cu(α,x) 66 Ga and nat Cu(α,x) 65 Zn reactions were confirmed while in the case of the nat Cu(α,x) 67 Ga reaction a new spline fit was calculated and given as new recommended cross sections.…”

Abstract. An upgrade and validation test of the recommended cross section database for charged particle reactions used for monitoring incident particle beams, published by the IAEA in 2001, is presented. In this upgrading process experimental cross sections published earlier, and not yet included in the evaluation work, or data measured recently were collected and added to the initial database in order to improve the quality of the recommended data. In the study 8 proton, 5 deuteron, 3 helium-3 and 6 alpha particle induced monitor reactions on Al, Ti, Fe, Ni and Cu targets were included. In general the newly compiled experimental results support the previous recommended data, but in a few cases they influence the decision and result in a slightly different group of selected cross section data sets and hence in new recommended cross section values. Spline fitting method was used to calculate the new recommended data from the selected data sets. For benchmarking and validation of the recommended cross section data, experimental thick target yields were collected from literature and some were newly measured. All data sets were critically compared with the integral thick target yields deduced from the recommended cross sections. In this paper only one reaction for each type of bombarding particles is discussed. A comprehensive paper will be published elsewhere including the results for all the 22 investigated reactions.
