    "abstract": "A new semiclassical approach to ionization by an oscillating field is\npresented. For a delta-function atom, an asymptotic analysis is performed with\nrespect to a quantity h, defined as the ratio of photon energy to ponderomotive\nenergy. This h appears formally equivalent to Planck\u0027s constant in a suitably\ntransformed Schroedinger equation and allows semiclassical methods to be\napplicable. Systematically, a picture of tunneling wave packets in complex time\nis developped, which by interference account for the typical ponderomotive\nfeatures of ionization curves. These analytical results are then compared to\nnumerical simulations and are shown to be in good agreement.",
