TīmeklisThe width of individual Lamb dips, consisting of single hyperfine transitions, is about 1.5 MHz. This cor- responds with a spectral resolution of 7 x 10’ which is an order of magnitude larger than we could obtain by a stronger collimation of the molecular beam [ 41. The observed linewidth of 1.5 MHz is due to several effects. TīmeklisThus, the nonlinear dependence of the Lamb dip width on pressure allows to get the set of data characterizing parameters of elastic and non-elastic collisions from …
