Query: Exchange Cross Sections for Hard Binaries   We present results on the exchange cross section for the interaction between
a hard binary and a field of single stars, for arbitrary masses. The results
are based partly on extensive numerical scattering experiments, and partly on
analytic estimates of the mass-dependence of the cross section. They can be
used to estimate the rate of exchange in an arbitrary mixture of masses,
provided that the binary is hard.
