摘要：

We present a simple model of molecular beams produced by a supersonic expansion of binary gas mixtures with one component diluted, The model leans on the nonequilibrium sudden-freeze dynamics developed for neat gas expansions. It provides handy expressions for quantities such as terminal temperatures, velocity slip, enrichment factor, and beam intensity. A comparison with measured properties of I2 Seeded in rare gas beams illustrates the reach of the model.
