\section{Experiment}  Neon, Argon, and Mercury were tested in three independent experiments. Monatomic gases were used in order to prevent molecular transitions. If a molecular transition were to occur, it is likely that some of the energy lost in the inelastic collisions would results from molecules separating into singular atoms, thus complicating the analysis. A general circuit diagram for the experimental setup is shown in Figure 1, containing all the elements previously discussed. Figure 2 shows the specific circuits used in each experiment. They are all relatively similar, save a few specific modifications. Mercury is the only element for which a heating chamber is required, since it is a liquid at room temperature. The heating chamber causes the room temperature mercury to undergo a phase transition, so that it may be used for study. In addition, Mercury is the only element that requires only one grid. For all elements, fixed value DC voltage sources and potentiometers were replaced by constant current/constant voltage power supplies with adjustable voltages. A current preamplifier was introduced in the experimental setup for Neon and Argon. An attempt to refine the observed signal was made using a variety of methods, so that it might be possible to resolve fine structure of the different energy levels. While some of this fine structure is clearly visible in the collected data, not enough data was collected for the observed fine structure to be quantifiable.
