A simple potential model proposed for the elastic scattering of positrons off rare-gas atoms is used to compute low-energy phase shifts and differential scattering cross sections [sigma]([theta]) for positrons incident on [sub 10]Ne, [sub 18]Ar, and [sub 36]Kr at energies 20, 3.4, and 6.67 eV, respectively. The calculated results for [sigma]([theta]) are in good agreement with currently available experimental values and are as reliable as the numbers obtained from much more elaborate calculations. It is pointed out that an important virtue of the present model is its simplicity.
