Deactivation rate of I2 molecules (X, ν ≥ 30) in the medium of a chemical oxygen-iodine laser

The effective deactivation rate constants are calculated for I-2(X) molecules at vibrational levels with nu >= 30 colliding with N-2 and O-2 molecules in the medium of a chemical oxygen - iodine laser. The calculated constants (4 x 10(-12) cm(3) s(-1) and 3 x 10(-12) cm(3) s(-1)) are less by half plus than the corresponding constants found earlier in the paper of Lawrence et al., where the dissociation of I-2 was neglected in calculations.
