    "abstract": "We calculate exact 3-D solutions of Maxwell equations corresponding to\nstrongly focused light beams, and study their interaction with a single atom in\nfree space. We show how the naive picture of the atom as an absorber with a\nsize given by its radiative cross section $\\sigma =3\\lambda ^{2}/2\\pi $ must be\nmodified. The implications of these results for quantum information processing\ncapabilities of trapped atoms are discussed.",
