Query: Study of Rb - vapor coated cell; atomic diffusion and cell curing
  process   We present the results of the study of an optical resonant cell filled by a
vapor of the Rb atoms and coated with a non-stick polydimethylsiloxane (PDMS)
polymer. We show that it is possible to define correctly the diffusion
coefficient of the atoms in the coating, using geometric parameters of the cell
and the vapor density in the cell volume only. The dependence of the diffusion
coefficient on the cell curing time is presented. It is shown that the
mysterious cell curing process can be explained in terms of the polymerization
of the polymer coating by alkali atoms. Anomalous long dwell time of the Rb
atoms on the PDMS coating is discussed as well.
