Using the Glauber theory and based on an independent alpha particle model, we have calculated the differential cross sections of ..pi../sup -/--/sup 16/O elastic scattering at three incident energies of the pion (T/sub ..pi../ = 110, 180, 220 MeV). We have used two-body amplitude F/sub pialpha/ as the basic input to parametrize the semi-empirical equation. The parameters can be obtained by fitting the ..pi..-..cap alpha.. elastic scattering data. Our results are in good agreement with the experimental data and the extent of agreement is comparable to that obtained in the previous optical potential calculations using pion-nucleon amplitude as input.
