A set of experiments investigating diffusion of alkali atoms in the noble gases is reported. A cesium gradient in the cell was induced by electrodeless pulse discharge. In the transient signal of absorption, corresponding to the ^2S_{1/2}-n^2P_J transitions, five diffusion modes were observed. The diffusion coefficient D of cesium in helium and argon has been measured in a spherical cell filled with a buffer gas of 2.5 to 30 hPa and for temperatures in the range from 275 K to 400 K.

A new method of simultaneous determining of the diffusion coefficient and the reflection coefficient of atoms from the reservoir walls is presented. The diffusion coefficient of cadmium atoms in the ground state in buffer noble gas atoms such as Ne, Ar, Kr, and Xe and reflection coefficient of Cd atoms from the quartz cell wall in the temperature range 350-550 K were determined. Experimental values of diffusion coefficient are compared with theoretical ones calculated from available potentials.
