| Popis: | The interaction of 6328‐A laser radiation with excited atoms in a He‐Ne gas discharge leads to a sizeable change in the population of the 3s2 and 2p4 levels of Ne. Population of levels connected to the upper and lower laser levels through radiative and nonradiative electronic and/or atomic collisional processes will be perturbed also by the population changes of these two levels. By studying the intensity changes of spontaneous emission from the 3s2 and 3s3 levels as a function of current and pressure, we obtained the total relative atomic and electronic deexcitation rates of the 3s3 level. We also studied the collisional coupling between the 3s2 and 4d4 levels of Ne (the ion cores of which are in two different states) to find the total atomic and electronic deexcitation rates for the 4d4 level. The electronic coupling between these two levels was found to be weaker than between the 3s2 and 3s3 levels, suggestive of a weak selection rule. |
