Svinarenko A. Spectroscopy of autoionization states of heavy atoms and ions with account of effects of collisions, chaos and external fields

Paper is devoted to carrying out theoretical foundations of new direction - relativistic spectroscopy of autoionization states AS of heavy atomic systems with accounting effects of external electromagnetic fields, atomic collisions and quantum chaos. Based on a new QED perturbation theory and energy approach it is developed a precise decay theory of AS for atoms in a free state and in an external electric field, a new approach to calculating collisional shift and broadening parameters for spectral lines in a buffer gas medium. There are firstly obtained new data on energy, radiation-autoionization paraneters for Не, barium, thallium, lead, lanthanide atoms (ytterbium, thulium) with discovery of new effects of resonances broadening chaos.
