摘要: In the recent years problem of observation quasimolecules and quasimolecular Roentgen emission in heavy ion-atom collisions was very important view electronic structure quasiatoms with effective atomic numbers much higher than 100 for new Processes quantum electrodynamics strong electromagnetic fields. The formation radiative decay inner-shell vacancies energetic manifest themselves x-ray spectra. drastic change binding energies at small internuclear distances causes a collision broadening characteristic lines colliding atoms. Compared thermal energies, ion this effect becomes so that notation has been introduced, namely continua or molecular orbital (MO) radiation. These have extensively studied during last few years. Some their properties such as energy limits yields can be estimated qualitatively simple way from correlation diagrams orbitals times.
