Anyone can buy UV-C lamps with a wavelength of 254 nm. Now, the energy to dissociate molecular hydrogen to atomic hydrogen is 4.52 eV, which corresponds to a wavelength of 274 nm. So a UV-C lamp should do the trick. The question is how efficiently? Cross sections? The easiest way to get an answer may be to try.
Here's my setup for producing deuterons: UV-C (the bare lamp should be inside the reaction chamber filled with D2 gas) to dissociate the D2 and at the same time electron bombardment from a heated filament cathode (and a voltage of several kV between anode and cathode) and alpha particles from Am-241 buttons, that I scavenged. Should be reasonable population of deuterons then.
Pressure? I will try with 1-10 Pa, and then upward to 100 Pa and higher and see what happens. If anything.
Comments?
Anyone in Europe who can sell me deuterium gas? Or in the US?
Use UV-C lamp to dissociate D2 molecules?

Yes you can disassociate the h2 to h but it is not ionised
I gave you the first ionisation energy in my previous answer.
Yes electrons with a few tens of volts of energy will ionise your hydrogen. No amount of UVc will ionise it. If it did we would have one hell of a pink sky above us.
