title: Small signal gain and vibrational relaxation for (13)CO(2).
abstract: We have determined the small signal gain for the P(18) transition of the (13)CO(2) and (12)CO(2) isotopes for identical pumping conditions in an x-ray preionized discharge amplifier. We have also determined vibrational-relaxation rate constants for He, N(2), and (13)CO(2) from the decay of the small signal gain on the P(18) transition of (13)CO(2) in the same x-ray preionized discharge amplifier. The vibrational-relaxation rate constants for N(2) and (13)CO(2) on the (13)CO(2)P(18) transition at 11.1 microm are a factor of 3 faster than the corresponding rate constants for the (12)CO(2) isotope.
