Cross section measurement of alpha particle induced nuclear reactions on natural cadmium up to 52 MeV

Abstract

Cross sections of alpha particle induced nuclear reactions have been measured on thin natural cadmium targets foils in the energy range from 11 to 51.2MeV. This work was a part of our systematic study on excitation functions of light ion induced nuclear reactions on different target materials. Regarding the cross sections, the alpha induced reactions are not deeply enough investigated. Some of the produced isotopes are of medical interest, others have application in research and industry. The radioisotope Sn is a very important theranostic (therapeutic + diagnostic) radioisotope, so special care was taken to the results for that isotope. The well-established stacked foil technique followed by gamma-spectrometry with HPGe gamma spectrometers were used. The target and monitor foils in the stack were commercial high purity metal foils. From the irradiated targetsSn, Sn,Sn, In,In, In,In, In,In, In,In, In,Cd and Cd were identified and their excitation functions were derived. The results were compared with the data of the previous measurements from the literature and with the results of the theoretical nuclear reaction model code calculations TALYS 1.8 (TENDL-2015) and EMPIRE 3.2 (Malta). From the cross section curves thick target yields were calculated and compared with the available literature data.

Recommended nuclear data for medical radioisotope production: diagnostic positron emitters

“…127 [280][281][282][283] together with the TENDL calculations. One dataset was rejected (Duchemin et al [282], values too low), while another became available after the evaluation cut-off date and therefore was not included (Ditrói et al [283]). The two remaining sets were used in the statistical fitting procedure, and these selected data and their experimental uncertainties are shown in Fig.…”

“…Four experimental datasets for the 108 Cd(α,2n)110 Sn reaction available in the literature[280][281][282][283], and TENDL calculations Two selected experimental datasets for the 108 Cd(α,2n)110 Sn reaction[280,281] with the Padé fit (L = 10, N = 24, χ 2 = 1.99, solid line) and estimated total uncertainties in percentages, including 4% systematic uncertainty (dashed line, right-hand scale)…”
