At pressures of a few Torr or less, the principal atomic emission lines of argon are the 106.67 and 104.82 nm lines with the lower wavelength line being approximately twice as intense as the 106.67 nm emission; Diebler V. H. and Reese R. M. , J. Res. Natl. Bur. Stand. 68A, 409 (1964).

The most probable metastable species having sufficient energies to dissociate SF₆ are the ³P₂ (11.54 eV) and ³P₀ (11.72 eV) states of argon.

Experimentally, the probability of quenching of Ar(³P_0,2) metastables by a glass surface was found to be 0.97; Allison W. Dunning F. B. , and Smith A. C. H. , J. Phys. B5, 1175 (1972).

After emerging from the discharge, the argon is subsequently deactivated to its ground state and condensed onto the 8°K window and must therefore be taken into account in the calculation of the final M/R (M = moles matrix, R = moles solute) ratios. An additional advantage realized when argon is used both as an excitation source and a matrix is that any mixed-matrix effects are avoided.
