Abstract：
In this paper,the η-N interaction potential via the Channel:N*ηN is derived within the framework of quantum field theory.By using this η-N S wave scattering length and the potential well depth of η-meson in nuclear matter are calculated.It is shown that the theoretical value of the η-N S wave scattering length is in good agreement with that obtained by analysing the πN scattering experimental data and our computational result for the potential well depth of η-meson in nuclear matter is about the same as other theoretical predictions for finite nuclei.
