Energy independent first-flight transport kernels are evaluated for a spherical region with an R-2 density distribution. The uncollided angular flux distribution is obtained and integrated for a source distribution that is proportional to the density to give the uncollided, emitted particle flux and current density. These are useful for the calculation of mass, energy, and momentum carried away by fast particles born in the medium. The data are relevant to estimate escape from weakly bound atmospheres such as comet comae, dilute circumstellar envelopes, and some unconfined laboratory plasmas.
