Determining the coefficients of ambipolar ion diffusion by the method of laser optogalvanic spectroscopy in a luminous gas-air flame

The coefficients of ambipolar diffusion of lithium, sodium, nickel, indium, platinum, and lead ions were measured by laser optogalvanic spectroscopy in the upper cone of a luminous gas-air flame at atmospheric pressure in the absence of an electric field in the flame. The coefficients of diffusion and mobility of the singly charged ions of these elements were calculated from the experimental data.
