Temperature dependent radio-frequency size effect measurements have been performed on high-purity, single crystal antimony plates at thicknesses of 0.592 mm, 0.347 mm, and 0.238 mm. The natural logs of the amplitudes of the data are found experimentally proportional to T('2) in agreement with previous measurements. However, the data are analyzed according to a model in which the electron-phonon scattering frequencies are proportional to T('3), with the explanation that the T('2) behavior is due to the small pieces of Fermi surface in antimony. The electron-phonon scattering frequencies are determined for both holes and electrons and are found to be highly anisotropic in each case. Copies of the computer programs used in the data analysis are included in Appendix I.
