I will look at the spectrum, there must published data, I just need to find
a source.

Thanks

I am building a better spectrometer. Will fire up next week. Hope for a
better signal to noise.

It should work, over 2 angstroms difference in the balmer line.

It just occured to me with such equipment it would be fairly easy to try isotopic enrichement of water, and then determine how successful by a discharge in the hydrogen.

A little off topic, but I thought it might be a cool experiment.

Beautiful picture, and I have often wondered what the spectrum looks like. Do you have enough resolution to measure the Dopler broadening and get an estimate of temperature?

We used an Ocean Optics spectrometer at EMC2 as well. I was hoping to measure Doppler broadening of the H beta peak with it. Never did get definitive results. Ions emit light when they recombine, and I think the high energy ions that would make the broadening don't recombine much.

Let me know if you ever detect broadening, and how you gathered enough light to do it.
