Relative-Velocity Distributions for Two Effusive Atomic Beams in Counterpropagating and Crossed-Beam Geometries
Figure 1
(a) shows relative velocity distributions for two identical beams (sodium with K), for crossed beams (cb) and for counter-propagating (cp) beams, respectively. The arrows indicate the mean relative velocity. (b) shows relative velocity distributions for the two configurations where a sodium beam with K collides with a potassium beam with K.
