Krasylynets' V. Processes of electron excitation of autoionizing states in lithium atom.

Object of investigation: lithium atom.Aim of studies: to perform the precise investigations of electron excitation of autoionizing states (AIS). Method of investigation: electron spectroscopy. Scientific novelty of results: technique of measuring the AIS excitation functions (EF) has been developed and applied. A resonance structure in EF has been revealed and interpreted. The existence of Li- ion resonances in the autoionizing energy region has been proven and spectroscopically identified.The absolute excitation cross sections for AIS have been obtained. The post-collision nteraction (PCI) i effect has been studied with high accuracy. The qualitative PCI model based on the crucial role of Li- resonances has been suggested.Implantation: planned. Sphere of application: astrophysics, laser technique, plasma engines, energy transformers etс.
