The ORNL ion-atom merged-beams apparatus has measured benchmark absolute electron capture cross sections for the multicharged ion N⁴⁺ on D from 1.2 eV/u to 982 eV/u (M. S. Huq, C. C. Havener, and R. A. Phaneuf, Physical Review A, 391725 (1989)). Due to an estimate that the cross section may rise at low energies and also that there may be structure in the total cross section, relative measurements were also made with the merged-beams apparatus from 1.4 eV/u to 301 eV/u (L. Folkerts, M. A. Haque, C. C. Havener, N. Shimakura, and M. Kimura, Physical Review A 51 3685 (1995)). These new measurements were made with an improved apparatus resulting in more accurate relative cross sections. The energy dependence of the old measurements was verified and no structure at low energies was observed. There is, however, evidence of structure at 100 eV/u.
