Small signal gain and vibrational relaxation for (13)CO(2).
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.
