Abstract

In this present study we investagate pion-nucleuse elastic scattering by using the optical model for 12C, 16O, 28Si and 40,44,48Ca in the kinetic energy range of 114 to 292MeV. The Krell-Ericson transformation provies a local potential that is excatily equavelant to the nonlocal Kisslinger-type potential form based on phase shift analysis. Johnson and Satchler modified Krell-Eriscon transformation to include some corrections. Kisslinger local potential is constructed by the sum of the contribution of s-wave and p-wave pion-nucleon interactions. A FORTRAN program is constructed to calculate the local Kisslinger potential for pion-nucleus interaction for first- and second- order interactions. The constructed potential takes into account all considered corrections made by others such as Coulomb correction, Perey factor and Ericson-Ericson Lorentez-Lorentez effect. The sensitivity of cross section to different forms of target densities are studied. Also, the effect of neglecting second-order parameters is studied. Good reproductions of the data are obtained by using both first- and second order parameters. The cross section is produced well with all densities.
