The asymmetry parameter A in ..pi../sup -/p elastic scattering at incident pion laboratory kinetic energies T/sub ..pi../ of 98, 238, and 292 MeV and in ..pi../sup -/p charge-exchange scattering ..pi../sup -/p..--> pi../sup 0/n at T/sub ..pi../ = 238, 292, and 310 MeV have been measured over a wide range of scattering angles (typically from about 60/sup 0/ to 130/sup 0/ c.m.) with a polarized proton target. The data have been used in an energy-independent phase-shift analysis to improve the precision of the pion-nucleon phase shifts, to set new limits on violation of isospin conservation in the pion-nucleon S wave, and to confirm significant charge dependence in the P/sub 3/2/ wave.
