    "abstract": "The transition probability for the emission of a Bessel photon by an atomic\nsystem is calculated within first order perturbation theory. We derive a closed\nexpression for the electromagnetic potentials beyond the paraxial approximation\nthat permits a systematic multipole approximation . The matrix elements between\ncenter of mass and internal states are evaluated for some specially relevant\ncases. This permits to clarify the feasibility of observing the rotational\neffects of twisted light on atoms predicted by the calculations. It is shown\nthat the probability that the internal state of an atom acquires orbital\nangular momentum from light is, in general, maximum for an atom located at the\naxis of a Bessel mode. For a Gaussian packet, the relevant parameter is the\nratio of the spread of the atomic center of mass wave packet to the transversal\nwavelength of the photon.",
