Extension of activation cross section data of long lived products in deuteron induced nuclear reactions on platinum up to 50 MeV

Abstract

In the frame of a systematical study of light ion induced nuclear reactions on platinum, activation cross sections for deuteron induced reactions were investigated. Excitation functions were measured in the 20.8 -49.2 MeV energy range for the nat Pt(d,xn) 191,192,193,194,195,196m2,196g,198g,199 Au, nat Pt(d,x) 188,189,191,195m,197m,197g Pt and nat Pt(d,x) 189,190,192,194m2 Ir reactions by using the stacked foil irradiation technique. The experimental results are compared with previous results from the literature and with the theoretical predictions in the TENDL-2014 and TENDL-2015 libraries. The applicability of the produced radio-tracers for wear measurements has been presented.

Experimental and theoretical cross section data of deuteron induced nuclear reactions on platinum

“…2). A good agreement with the earlier experimental studies [6,7] in the overlapping energy interval is seen. Because none of the theoretical model code gave acceptable predictions for the experimental values an estimated prediction from the systematics has also be presented in Fig.…”

“…(d,xn) 196m2 Au reaction Direct production cross-sections for the T 1/2 = 9.6 h isomeric state 196m2 Au are shown in Fig. 5 and agree well with the Ditroi et al [6] data. All theoretical model codes recognize the two maxima, but all overestimate the experimental values.…”

“…In our last investigation up to 50 MeV [6] we could deduce only scattered data for some activation products and for some reactions significant disagreements were found with earlier experimental data. During a recent investigation of activation data on other target elements we got the possibility to obtain additional results on platinum in the 35-49 MeV energy range.…”

“…The comparisons result in different conclusions for each reaction, which is hard to explain. Some more detailed discussions are available in our previous work [6]. Therefore, in the summary we present only general conclusion on the predictive capability of the model calculations.…”

“…Experimental activation cross section data of proton and deuteron induced reactions on platinum for production of medically relevant radioisotopes, for thin layer activation technology and for generally used activation data libraries [1][2][3][4][5][6] were reported by us earlier. The goal of this study was to clear the disagreement in our earlier measurement, and to compare all data with different theoretical models.…”
