METHOD     (DIFFR) Two coherent beams traverse two different      2162200100036 
            path lengths in a gaseous sample of the material      2162200100037 
            to be studied. This causes a phase shift between      2162200100038 
            the two beams. By forcing these two beams to          2162200100039 
            interfere this phase shift can be determined from     2162200100040 
            the beam intensity oscillations as a function of      2162200100041 
            the density (i.e. the pressure, provided the          2162200100042 
            temperature is monitored) of the sample. For          2162200100043
