D001400400008 2) the least square fit reported in bnwl-1685 is not D001400400009 recommended for use due to the inclusion of a D001400400010 resonance near 2 MeV. D001400400011 3) more thin-target experiments are required. D001400400012 measurements at energies down to 20kev would be of D001400400013 great value in determining the extrapolation of cross-D001400400014 section to very low energies. D001400400015 4) experiment on t(t,2n) should be performed together D001400400016 with D(t,n) reaction, because for confirmation of D001400400017 older T(d,n) measurement. D001400400018 *following measurements have been checked. D001400400019 the references are summarized in ''rel-ref'' with otherD001400400020 evaluation works.
