    "abstract": "We have found recently that, in a supersonic expansion of a mixture of two\nmonoatomic gases, the parallel temperatures of the two gases can be very\ndifferent. This effect is large if the seeded gas is highly diluted and if its\natomic mass is considerably smaller than the one of the carrier gas. In the\npresent paper, we present a complete derivation of our theoretical analysis of\nthis effect. Our calculation is a natural extension of the existing theory of\nsupersonic cooling to the case of a gas mixture, in the high dilution limit.\nFinally, we describe a set of temperature measurements made on a beam of\nlithium seeded in argon. Our experimental results are in very good agreement\nwith the results of our calculation.",
