Pseuodpotential molecular-structure calculations have been used to obtain the low-lying interaction energies for NaH/sup +/. The wave functions were used to calculated accurate radial and rotational coupling matrix elements. Scattering calculations which include electron translational factors were performed using up to 8 coupled channels for laboratory energies 0.1 to 10 keV. Electron capture from ground-state Na 3s yields cross sections in the 10/sup -15/-cm/sup 2/ range of which the dominant products are H 2s and H 2p. Electron capture from excited Na 3p does not show an enhanced cross section relative to capture from the ground state even though the energy gap ..delta..E(R = infinity) to the dominant electron-capture channel is reduced from 1.74 to 0.36 eV.
