The method presented in the first paper of this series for computing distributions in steady-state effusive flows was applied to beam-scattering chambers of especially simple geometry having identical long, narrow slits of negligible channel length. The results are presented as correction factors $\ensuremath{\alpha}$ which, when multiplied by the chamber length, give the effective length of scattering path through an attenuating medium of uniform density equal to that in the scattering-gas source. Predictions of the calculations compare well with scattering measurements made with a chamber of variable length. |
