The ionization and excitation of argon atoms and electron heating ahead of a shock front are analyzed. Radiative processes (line and continuum radiation) and collisional processes (electron--atom collisions) are taken into account. The fact that the gas density is higher in the relaxation zone than ahead of the shock front and the reflection of the line and continuum radiation from the tube walls are also taken into account. A system of ordinary differential equations for the densities of the 4$sup 3$$P$$sub 1$ and 4$sup 1$$P$$sub 1$ states of the argon atoms, the electrons, and the electron temperature are solved numerically to find the profiles ahead of a shock front for pressures in the range p=1--10 torr and Mach numbers in the range M=12--30. The results are compared with experiment. (AIP)
