Coherent Population Trapping Resonances in Cs Atomic Vapor Layers of Micrometric Thickness

Table 1

Calculated values for 133Cs: vapor pressure , atomic density , most probable Cs atomic velocity , collision rate , mean free path between the collision of two Cs atoms , time between two atomic collisions with the cell wall (having : the thin-cell window diameter), time between two atom collisions , and the number of collisions Cs-Cs during a complete flight along the cell diameter .
