Slow collisions ofH−andD−with Na and K

Relative cross sections for charge transfer and electron detachment in collisions of ${\mathrm{H}}^{\mathrm{-}}$ and ${\mathrm{D}}^{\mathrm{-}}$ ions with Na and K atoms have been measured in the energy range from 2 to 300 eV. Measurements of the differential elastic cross sections for collisions of ${\mathrm{H}}^{\mathrm{-}}$ with Na are also reported for energies around 10 eV. A two-state perturbed-stationary-state calculation has been performed and compared with the experimental results and a previous calculation.
