Abstract: A theoretical model for the expansion of a plasma with three and multiple electron temperatures is developed. The three and multiple peak structures exhibited in ion velocity distributions, which have frequently been observed experimentally, have successfully been represented by the self similar solutions. The principal features and available range of the solutions are discussed.
