摘要：

Basing on new experimental results on nonlinear transmission of photosynthetic particles measured with the pump- and probe-beam technique a reaction kinetic three-level model involving one- and two-particle excitations is developed to describe the observed phenomena quantitatively. It is shown that the nonlinear effects are caused by a competition between the one- and two-particle excitations. The physical nature of the two-particle excitations is discussed as well their role in a coherent energy transfer process in photosynthetic membrane.
