【 摘 要 】

Synopsis The influences of Breit interaction on the total cross section and linear polarization of highly charged Ca15+, Xe49+, and W69+ ions in the electron impact excitation process are calculated by fully relativistic distortedwave program REIE06. It is found that the influence of Breit interaction on the linear polarization is more obvious with the increase of atomic number Z.
