Here we present a quantum electrodynamics (QED) model involving a large-detuned single-mode cavity field and n identical two-level atoms. One of its applications for the preparation of the multi-particle states is analyzed. In addition to the Greenberger-Horne-Zeilinger (GHZ) state, the W class states can also be generated in this scheme. The further analysis for the experiment of the model of n=2 case is also presented by considering the possible three-atom collision.
