New excitation functions measurement of nuclear reactions induced by deuteron beams on yttrium with particular reference to the production of 89Zr

Abstract

New excitation functions measurement of nuclear reactions induced by deuteron beams on yttrium with particular reference to the production of 89 Zr.We investigated 89 Zr production induced by deuteron beams on yttrium targets at energies up to E d = 32 MeV using the stacked-foil activation technique. Cross sections of the following nuclear reactions 89 Y(d,2n) 89 Zr, 89 Y(d,3n) 88 Zr and 89 Y(d,x) 88 Y have also been measured. Based on the measured values, we determined the thick target yields for 89 Zr and 88 Zr which is the main contaminant associated to the production of 89 Zr.

Activation cross section measurement of the deuteron-induced reaction on yttrium-89 for zirconium-89 production

“…2 with the previous studies [3][4][5][6][7][8]10] and the TENDL-2017 values [19]. Our experimental data are consistent with the latest four works [3][4][5][6]. The TENDL-2017 values are larger than all experimental data in the energy region between 6 and 20…”

“…The cumulative cross sections including contributions from 89m Zr were determined and are shown in Fig. 2 with the previous studies [3][4][5][6][7][8]10] and the TENDL-2017 values [19]. Our experimental data are consistent with the latest four works [3][4][5][6].…”

“…We confirmed formations of 89 Zr, 88 Zr, 90m Y, 88 Y and 87m Sr by the gamma-ray spectrometry. Their production cross sections including uncertainties are listed in Table 3 and displayed together with the previously published data [3][4][5][6][7][8]10,[16][17][18]. The experiment published in 1973 [9] shows large discrepancies from the other data sets.…”

“…[2] and references therein). In contrast, only eight experiments focused on the latter can be found in the literature survey [3][4][5][6][7][8][9][10]. The published excitation functions are not always entirely consistent and only a few previous studies measured data beyond 20 MeV.…”
