In order to provide the desired isotope separation, the deflection section 14 should provide enough displacement or velocity change to allow physical separation of the excited molecules from the molecules which are unaffected by the laser irradiation with a sufficiently large through put to be useful in the sense of providing a significant volume or {HEAD ~ quantity} of {TAIL ~ enriched gas output}
