Up to the first perturbative order in the quartic interaction (interaction parameter $\\lambda$), we use the formalism of {\\it dressed} states introduced in previous publications, to obtain for a large cavity explicit $\\lambda$-dependent formulas for the particle radiation process. These formulas are obtained in terms of the corresponding exact expressions for the linear case.
