We determined accurate He-broadening parameters and collisional cross secti
ons for the P(2) line in the fundamental band of CO at room temperature and
at intermediate temperatures down to 11.5 K. We also determined a precise
value for the temperature dependence of the line-broadening parameter on (T
)(-n) with n equal to 0.548 +/- 0.010. Our results validate the microwave r
esults for the J = 1 to J = 2 rotational transitions measured over the same
range of temperatures which were reported previously by Beaky et al. (1996
, J. Chem. Phys. 105, 3994-4004). (C) 2001 Academic Press.
