dc.description.abstractBelow 80 K the pressure broadening cross section for HDO-He collisions is predicted to be less than 10 ${\AA}^{2}$. This is quite small for a microwave transition and suggests that the line may, at low pressures, narrow with increasing pressure (Dicke narrowing). We have employed collisional cooling to measure the lineshape of the $HDO 1_{01} - 11_{11}$ transition between 2 and 80 K. Initial results for the high pressure data indicate that the theoretical predictions for the cross section are valid. A more detailed analysis that investigates non-Lorentzian contributions to the lineshape will be discussed.en_US
