Collision-based spectroscopy of a
beam with a target ( Ar) has been performed in the 35–800-nm wavelength region. Twenty-five new Xe vi lines and twenty-two new Xe vii lines were classified, twelve new energy levels of Xe vi and nine new energy levels of Xe vii were established, and one energy level of Xe vi was revised from the classified transitions. The analysis was supported by Hartree–Fock calculations.
