Theoretical absorption spectra for Ne+2, Ar+2, Kr+2, and Xe+2 in the near ultraviolet

Abstract
Near‐ultraviolet absorption spectra for the I(1/2)u→II(1/2)g transition have been calculated for Ne+2, Ar+2, Kr+2, and Xe+2 using ab initio configuration interaction methods. The spectra are all similar except that the position of maximum absorption shifts to longer wavelength for the heavier rare gases. The absorption cross sections are tabulated at the wavelengths of the KrF, XeBr, XeCl, and XeF lasers.
