Bill,I think this is an excellent topic
... I'm considering my approach to the final project, and am 99% sure that I will do something along the lines of computation / simulation. I have a strong background in programming, and have had lots of fun and success in simulating all sorts of classical physics scenarios. I'd like to expand my horizo ...

There is an obvious way to get such closely spaced spectral lines: they will be observed if the degenerate energy levels are not truly degenerate but separated in energy by a very small amount (Figure 9.4).
