Sulfur isotope enrichment by dissociative electron attachment
A mechanism is proposed for sulfur isotope enrichment experiments with lasers combining the selective vibrational heating capabilities of the laser with the electron attachment properties of the SF$sub 6$ molecule. It is suggested that isotope enrichment may be achieved by selective vibrational heating of one isotopic molecule by the laser, followed by its dissociative electron capture and subsequent removal from the mixture. A reasonable estimate for the extent of selective vibrational heating, together with a slight extrapolation of the known temperature dependence for the SF$sup -$$sub 5$/SF$sub 6$$sup -$ branching ratio, indicates that enrichment ratios of the order of 4500 may be achievable by this process.
