The neutron fluence spectrum used in the analysis to determine absolute cross section values was found to be erroneous. The same error also affects data in [1], and a separate correction will be published for that work. The corrected Maxwellian averaged cross sections (MACS) are listed in Table 1 and shown in Fig. 1. The corrected resonance capture kernels and unresolved cross sections are shown in Tables 3–7, and Fig. 2, respectively. The average resonance parameters determined from the resonance fits change slightly (within uncertainties). We obtain an average radiative width of [Formula presented] meV and [Formula presented] meV, an average s-wave spacing of [Formula presented] eV, and neutron strength functions of [Formula presented] and [Formula presented]. Uncertainties in the resonance kernels due to systematic effects are 3.9% below and 6.0% above 10 keV neutron energy, consisting of uncertainties due to Pulse Height Weighting (3%), normalisation (1%), sample enrichment (1%), and neutron flux (2% below, 5% above 10 keV). Total systematic uncertainties for the averaged cross sections are 6.2% and uncertainties for the Maxwellian averaged capture cross sections change correspondingly (see Table 2). Due to the small changes of at most 4% in the Maxwellian averaged capture cross section (smaller than the total uncertainty), all conclusions remain unaltered. The authors apologise for any inconvenience this caused. Updated data will be provided to the EXFOR database.
