Also, to be more precise, its the absorption cross section per hydrogen atom that i need.

Sort of. I wrote some code about this which technically works, i just need the exact number, but then a lot of other stuff came up that i had to do first, so i left searching for this value for later, which is now. And as i actually made lots of mistakes in my first thread, i thought better make...

Greetings, i need the absorption cross section for the absorption of an H-alpha photon by a hydrogen atom, in the correct state of course, which I'm pretty sure is neutral hydrogen, n=2. I am needing this for a project, so i also need a reliable source where this comes from. Thanks beforehand...

So I'm trying to use the excitation law of Boltzmann and the ionisation law of Saha to calculate stuff about what percentage of a quantity of hydrogen in ionised and in what energy state. I have the temperature and energy levels values, so i still need the: -statistical weight (degeneracy)...

I need help with something that i seemed to remember was fairly easy, but just can't seem to find the simple formula for: I have an amount of hydrogen atoms at a temperature of 10000 Kelvin. What percentage of them are ionised and what percentage of them are in the n=2 excited state...

ok wait, I'm getting confused, or mixing up my basic physics, so let me go more broad: Let's say we have a postiive hydrogen ion being radiated by light with a very broad wavelength range. What wavelengths will get absorbed and what is the corresponding absorption cross section?

euhm, this chart seems to just give spectral lines of hydrogen, while what i need are absorption cross sections, i.e. the measure of probability that the hydrogen ion absorbs a photon, this being dependent on the wavelength. I need this for a specific set of photon wavelenghts, one of which...

hello, i need the values for the absorption cross sections of positive hydrogen ions for a specific set of wavelengths, Halpha to start with. At first i thought finding this on the web was easy, but turns out to not be trivial at all. If you can help me, i also need the (reliable) source...
