We present cross sections for the direct charge-transfer process N{sup 4+}(2s)+H{r_arrow}N{sup 3+}(nl;n{sup {prime}}l{sup {prime}})+H{sup +} for center-of-mass collision energies between 0.1 eV/amu and 8 keV/amu. The results are in good agreement, at low energies, with merged-beams measurements for the total electron-capture cross sections in collisions of N{sup 4+} with hydrogen and deuterium targets. We also compare the calculated final-state cross sections with the results of recent translational energy spectroscopy measurements. The calculated final-state cross sections show good agreement with the experiment for ion projectile energies up to 8 keV. Our calculations suggest that the total electron-capture cross sections display Langevin behavior for collision energies below 0.4 eV/amu. {copyright} {ital 1997} {ital The American Physical Society}
