We studied the dissipative dynamics of a degenerate-level atom interacting with a single linearly polarized mode field in the dispersive approximation. It is found that the degeneracy of the atomic levels affects the dissipation of the system, of the atom and the field. The period of entanglement becomes much longer than that in the usual Jaynes-Cummings model dissipation. The degeneracy of the atomic level increases the maximum value of the degree of the statistical mixture.
