• An optical potential approach at low energy is attempted for the kaon-nucleus interaction. The optical potential is introduced by folding the finite range kanon-nucleon potential with the nuclear ground state wave function. The K^^--N potential considered is constructed to reproduce the free K^^--N scattering lengths. Using the optical potential we evaluate elastic cross sections of low energy kaon scattering by nuclei and complex level shifts of kaonic atoms. Both results obtained prove to be more consistent with experimental values than those given by the previous approach. In particular it is suggested that the real part of this potential is mainly attributed to the Yukawa type potential induced by the vector meson exchange apart from the imaginary part.
