Activation cross-sections of deuteron induced reactions on natGd up to 50MeV

Abstract

Activation cross-sections are presented for the first time fornat Gd(d,xn) 161,160,156(m+),154,154m1,154m2,153,152(m+),151(m+) T b, nat Gd(d,x) 159,153,151 Gd and nat Gd(d,x) 156 Eu reactions from their respective thresholds up to 50 MeV. The cross-sections were measured by the stacked-foil irradiation technique and by using high resolution γ-ray spectrometry. The measured values were compared with the results of theoretical models calculated by the computer codes ALICE-D, EMPIRE-D and TALYS (data from TENDL library). Integral yields of the reaction products were deduced from the excitation functions.

New developments in the production of theranostic pairs of radionuclides

“…Besides the application of the spallation process to the production of 152 Tb, many investigations on other possible production reactions have also been carried out. They deal either with cross section measurements of proton and deuteron induced reactions on gadolinium and dysprosium [161][162][163][164][165][166] or with chemical separation of radioterbium from gadolinium irradiated with protons [167], europium irradiated with α-particles [168] or lanthanum and cerium irradiated with 16 O-ions [169,170]. The (p,xn) reactions on gadolinium isotopes in the intermediate energy range appear to be promising.…”

Excitation functions for production of 46 Sc by deuteron and proton beams in nat Ti: A basis for additional monitor reactions

“…-Values for 46 Sc production that are not published and were obtained in studies by our group where the nat Ti(d,x) 48 V reaction was used as monitor and where the experimental circumstances are described in a journal article (16 publications, [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]). Some of these references include results for multiple irradiations at different incident energies.…”

“…The over-all uncertainties on cross section values for references [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] are 10-12% and are obtained by quadratic summation of the contributions of relative uncertainties on beam current, number of target atoms, decay characteristics, efficiency calibration and counting statistics as stated in the respective publications.…”

Production Cross-Section Measurements for Terbium Radionuclides of Medical Interest Produced in Tantalum Targets Irradiated by 0.3 to 1.7 GeV Protons and Corresponding Thick Target Yield Calculations

“…Tb-149 has properties suitable for targeted alpha therapy and PET imaging, while Tb-161 is a good candidate for targeted β-therapy and also suitable for SPECT imaging. These radionuclides can be produced e.g., by proton, deuteron or alpha induced reactions on natural or enriched gadolinium (2)(3)(4)(5)(6)(7), by neutron irradiation of enriched Gd-160 (8,9) or spallation reactions on materials like tungsten or tantalum (10)(11)(12)(13). The latter production method has been studied in this work in the framework of the ISOLDE facility at CERN, producing radioactive ion beams from 1.4 GeV proton-induced spallation reactions on a solid Ta target.…”
