In a crossed-beam experiment the total ionization cross section for the title systems has been investigated in the range 0.1{le}{ital E} (eV) {lt}=4 of collision energies. The population of the short-lived Ne{sup **}((3{ital p});{ital J}=3) state is produced by saturated optical pumping of the Ne{sup *}((3{ital s});{ital J}=2){leftrightarrow}Ne{sup **}((3{ital p});{ital J}=3) two-level system with a polarized laser beam, resulting in a well-determined distribution of the magnetic substates {vert bar}{ital J},{ital M}{r angle} with respect to the relative velocity {bold g}. By measuring the ion yield in the scattering center at five different orientations of the laser polarization (linear and circular) with respect to {bold g}, the data can be analyzed in terms of pure-state total ionization cross sections {sup 3}{ital Q{vert bar}{ital M}{vert bar}} corresponding to a single asymptotic state {vert bar}{ital J},{ital M}{r angle}.
