Eqn 2 is used to estimate the lowest excitation energy of Neon. Since, $\Delta E_{atom}=\Delta E_{electron}$, and all the values of $\Delta E$ should be equivalent. Thus to find the lowest excitation energy, a mean value was found between the three data points. Thus using the short mean free path  limit the lowest excitation energy is found to be approximately $19.54\pm3.2$. This value is not exceedingly better than the value found using the long mean free  path limit. To estimate $E_{a}$ when the mean free path, $\lambda$, is significant, an equation for the lowest excitation energy can be derived from equation 5. \begin{equation}  E_a = (0.5)\Delta E  \end{equation}
