    "abstract": "We derive the interaction Hamiltonian of a Laguerre-Gaussian beam with a\nsimple atomic system, under the assumption of a small spread of the center of\nmass wave function in comparison with the waist of the Laguerre-Gaussian beam.\nThe center of mass motion of the atomic system is taken into account. Using the\nproperties of regular spherical harmonics the internal and center of mass\ncoordinates are separated without making any multipolar expansion. Then the\nselection rules of the internal and of the center of mass motion transitions\nfollow immediately. The influence of the winding number of the\nLaguerre-Gaussian beams on the selection rules and transition probability of\nthe center of mass motion is discussed.",
