11. In Fig. 4 of Ref. 3, the theoretical data of Feickert et al. 2 are displayed and compared to the measured cross-section data. It appears to show good agreement between theory and experiment. However a careful comparison of the theoretical data plotted in Fig. 4 of Ref. 3 and the data given in Figs. 6(a) and 6(b) and 7(a) and 7(b) in Feickert et al., suggests that the two sets of displayed theoretical data are consistent only if the former authors used the conversion (Formula presented), where (Formula presented) is the collision energy given by the abscissa in Fig. 4 of Ref. 3, and (Formula presented) is the center-of-mass energy (used in the calculation of Feickert et al.). Instead, the experimental data are plotted with respect to the collision energy (Formula presented), where (Formula presented) amu is the reduced mass of the (Formula presented) ion-atom system, and not 14 amu, the mass of the nitrogen atom 12. Taking this correction into account the comparison between theory 2 and experiment is fair.

17. In Fig. 6 of Ref. 5 we plotted the calculated singlet charge-transfer cross sections and compared them to the measured values for the total, charge capture cross sections reported in Ref. 3. In transcribing the measured cross sections, in this figure, we erroneously assumed that the cross sections given in Ref. 3 are tabulated with respect to the values (Formula presented), where (Formula presented) is the mass of the nitrogen nucleus (see 11).
