Abstract
Experimental broad-band continuum emitted by electric-discharge Kr+Xe plasma is interpreted as the KrXe* and Xe2 molecules emission due to the 0+(3P1) ↦ 0+(1S0) bound-free transitions. Using the literature data for the 0+(3P1) and the 0+(1S0) internuclear potentials and a dipole moment function the relative intensities of the v, 0+(3P1) ↦e, 0+(1S0) transitions were calculated in relation to the transition wavelengths. It is noted that internuclear potentials for the Xe2 molecule used in the present work allowed one to describe the long-wavelength wing of experimental spectra under consideration quite adequately. As to the KrXe* model continuum which is associated with the short-wavelength region of the same spectra it proved to be shifted to short-wavelength side at 5–7 nm in comparison with experiment, and its width proved to be half of experimental one.
