What does it take for hydrogen to form from protons and electrons?

AI Thread Summary
Hydrogen formation from protons and electrons requires that they have minimal energy and velocity relative to each other, with reverse ionization needing energy below 20 electron-volts. The process involves the electron being captured by the proton, often facilitated by the emission of a photon. This phenomenon occurs frequently in electrified gas lamps and in the sun's surface layers. The discussion also touches on the relationship between proton-electron recombination and oxygen, particularly in the context of fuel cells. Further literature or resources on the capture process and related mechanisms are sought for deeper understanding.

Hi

What does it take for hydrogen to form from protons and electrons?

I have searched quite a bit and the only information that I have so far is from this webpage

http://www.Newton.dep.anl.gov/askasci/phy00/phy00843.htm

from the webpage
------------------------------
To form a hydrogen atom, it is required that the electron and proton have
almost no energy, almost no velocity relative to each other.
A hydrogen atom ionizes at less than 20 electron-volts of energy, so
reverse ionization requires energy less than about 20 electron-volts (eV)
AND freedom and luck to radiate a photon of the right energy to render the
electron "captured".
It happens all the time in every electrified gas lamp (fluorescents,
neons, mercury-arc, etc), and in the surface layers of the sun.

I have looked for proton electron
recombination
reverse ionization
capture
hydrogen formation

and countless other searches. I’ve looked at the Coulomb force but could not tease any useful information out of it. Nor did a search of Schrödinger solution.

There are 389 posts on this website with the word proton in it (now there is 390). The only post that I could find that alludes to this mechanism is

https://www.physicsforums.com/showthread.php?t=17973&highlight=proton

In this post, the question “So in order for the hydrogen proton and electron to recombine, they must combine with the O2 to form water?” is asked
And Russ Watters answers “Essentially yes”

Why must the recombination happen with O2?Any information or literature that could be suggested would be useful.
Thanks

That answer I gave was within the context of a fuel cell.

What was wrong with the answer quoted in the beginning of your post?
 
Thanks Russ

I am looking for more in depth information about the capture process.


I really don't expect an answer to the question but rather someone who can point me in the right direction, something to read.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
