Neutron resonances in181Ta AT 2?70 eV

Measurement and analysis of theAm241(n,γ) cross section with liquid scintillator detectors using time-of-flight spectroscopy at the n_TOF facility at

“…Older time-of-flight measurements are the transmission data sets from Derrien and Lucas [22] and from Kalebin et al [23,24], as well as the capture data from Weston and Todd [25] and from Van Praet et al [26].…”

“…In evaluated data libraries, ENDF/B-VII.1 [29] adopted the resonance parameters evaluated by JENDL-4.0 [30], which took into account the work of Jandel et al [27], whereas the parameters of JEFF-3.1.2 [31] are based on data from Refs. [22,23,25,26,[32][33][34][35][36]. Figure 1 shows the discrepancies between experimental and evaluated data sets in the 241 Am neutron capture cross section for the first three resonances, of which the parameters are given in Table I.…”
