    "abstract": "Quantum stochastic differential equations have been used to describe the\ndynamics of an atom interacting with the electromagnetic field via\nabsorption/emission processes. Here, by using the full quantum stochastic\nSchroedinger equation proposed by Hudson and Parthasarathy fifteen years ago,\nwe show that such models can be generalized to include other processes into the\ninteraction. In the case of a two-level atom we construct a model in which the\ninteraction with the field is due either to absorption/emission processes\neither to direct scattering processes, which simulate the interaction due to\nvirtual transitions to the levels which have been eliminated from the\ndescription. To see the effects of the new terms, the total, elastic and\ninelastic eloctromagnetic cross sections are studied. The new power spectrum is\ncompared with Mollow\u0027s results.",
