Abstract Positronium (Ps) formation cross section for positron scattering on potassium is calculated at low impact energies (0.2--15.0eV). The present calculation uses an optical-model method with an equivalent local polarization potential. The results for the Ps (n=1) and Ps (n=2) formation cross sections are calculated and compared with the experimental measurements and other theoretical results.
