Measurements of deuteron-induced activation cross-sections for IFMIF accelerator structural materials

The activation of W and Zr by deuterons at energies up to 20 MeV

“…1-10. They are compared to the results of previous authors [5][6][7][8][9][10][11][12][13][14] and to the evaluated data from EAF 2007 [15] and TENDL 2014 [16] libraries. All evaluated data are corrected/normalized to natural abundance of the sample…”

Investigation of the 27Al(d,x)24Na nuclear reaction for deuteron beam monitoring purpose

“…A correction factor of 0.02 was used for this adjustment which was cumulatively increased from the first foil to the last foil in the stacked samples. The production crosssections of 24 Na radionuclide is presented in Table 2 while the excitation function is plotted in Fig. 2 together with the earlier reported experimental data obtained from the EXFOR library [11] and the evaluated data taken from the TENDL-2015 library [12].…”

“…Error-bars are omitted for the experimental data taken from the EXFOR library for better visibility. Furthermore, the recommended cross-sections by Takacs et al [13] for 27 Al(d,x) 24 Na reaction is also potted in Fig. 2 for comparison. The population of the ground state 24g Na (T 1/2 = 14.997 h) is contributed by the direct reactions presented in Table 1, and by an IT decay (b I T = 99.95%) of its short-lived isomeric state 24m Na (T 1/2 =20.18 ms) within our investigated energy region.…”

Therefore, the measured production cross-sections are regarded as the sum of the ground and meta-stable states, 24(g+m) Na. The neutron rich 24g Na decays to the stable 24 Mg via an emission of β − particle (b β¯= 99.995%) followed by the emission of 1368.626 keV γ -line (I γ = 99.9936%) and 2754.007 keV (I γ = 99.855%) γ -lines.…”

The 2754.007 keV γ -line lies outside the detector calibration range, thus the intense 1368.626 keV γ -line released from the first excited state of 24 Mg was used to determine the cross-sections of 24g Na radionuclide.…”
