Abstract
High ionization of atoms and molecules is a requirement in several atomic and plasma studies and studies of radiation spectra, in the production of lasers and in industrial applications of various kinds. Most often, ionization of atoms is limited to the removal of the outermost electrons only, for doing which well-known techniques exist. Extraction of electrons from the core shells strongly bound to the atoms, especially the heavy atoms, is difficult. Removal of these electrons is however necessary to achieve a high level of ionization or total ionization demanded in several applications. The method of the present invention employs positron annihilation in flight as a means of eliminating the electrons of the core shells of atoms, especially in the case of elements of large atomic number, so that total or near-total ionization is possible. The method is particularly relevant in producing inner-shell ionization in plasmas and assembles of heavy ions.
