Pressure broadening and pressure shift parameters have been measured for CO in collision with helium over a wide range of temperatures. This temperature range includes the high temperature semiclassical regime in which the physics of the collision is properly described by Anderson-like theories as well as the low temperature regime in which new phenomena associated with quasibound states require a more complete quantum mechanical description. Experimental results will be compared to theoretical predictions generated from a variety of CO-He potential energy surfaces. The discrepancy between experiment and the best available potential energy surface will be discussed.
