WebAbstract. The spectrum of doubly ionized mercury (Hg III) has been studied in the wavelength region of 400 - 2000Å. The Hg III is Au II like ion with its ground configuration 5d10 (1 S 0) .The outer electron excitations are of the type 5d 9 n l(n >=5). Some low lying internal excitations 5d 8 6s 2 and 5d 8 6s6p have also been reported along with 5d 9 (6s, …
WebThe efficiency of the optimal mercury ionization scheme was measured, together with the efficiency of a new three-step three resonance ionization scheme for tellurium. The efficiencies of the mercury and tellurium ionization schemes were determined to be 6 % and >18 % respectively.
