We present ab initio quantal calculations of electron capture cross sections for collisions of ground and metastable states of {sup 14}N{sup 2+} and {sup 16}O{sup 2+} ions with H(1s), at collision energies 10{sup -2}<E<10{sup 2} eV/amu. The calculation for N{sup 2+}+H updates the previous one of Barragan et al. [Phys. Rev. A 70, 022707 (2004)] at 0.1<E<0.3 eV/amu. Total cross sections for both systems show large values of about 5x10{sup -15} cm{sup 2} at E<0.1 eV/amu, where they exhibit resonant structures.
