The pion-nucleus microscopic optical potential (OP), defined by the pion-nucleon scattering amplitude and by the generalized density distribution of a target nucleus that incudes internal degrees of freedom, is applied to construct the pion-nucleus differential cross-sections of elastic and inelastic scattering on the nuclei 28 Si, 58 Ni, 208 Pb at T lab = 291 MeV. Calculations are based on the relativistic wave equation and thus relativistic effects and distortions on the relative motion wave functions are taken into account. The respective experimental data are analyzed and the in-medium parameters of the elementary πN -amplitude are established and compared with those from the pion scattering on free nucleons.

Analysis is performed of calculations of the elastic scattering differential cross sections of pions on the 28 Si, 40 Ca, 58 Ni and 208 Pb nuclei at energies from 130 to 290 MeV basing on the microscopic optical potential (OP) constructed as an optical limit of a Glauber theory. Such an OP is defined by the corresponding target nucleus density distribution and by the pion-nucleon πN amplitude of scattering. The pion-nucleus cross sections are calculated by numerical solving the corresponding relativistic wave equation. The three (say, "in-medium") parameters of the πN amplitude, the total cross section, the ratio of real to imaginary part of the forward πN amplitude, and the slope parameter, were obtained by fitting the calculated cross sections to the respective experimental data. A difference is discussed between the best-fit "in-medium" parameters and the "free" parameters of the πN scattering amplitudes known from the experimental data on scattering of pions on free nucleons.
