THE DISSOCIATIVE EXCITATION PROCESSES IN COLLISIONS OF ELECTRONS AND HELIUM IONS WITH OXYGEN MOLECULES.
Accepted for publication May, 2002
ABSTRACT. Absolute cross sections for dissociative excitation processes of oxygen atomic and ionic lines in the collisions of e -O2 and He+-O2 are determined. The high intense oxygen ionic line OII (83.4 nm) has been observed. In case of electrons impact a doubly charged oxygen ionic line OIII (70.5 nm) has been observed too. For He+-O2 collisions the experimental results are interpreted qualitatively in terms of quasidiatomic approximation.
