I am really stuck on setting up the problem & equations to solve, can someone please help me out with this beginning step?
The question is:
1) A plasma out in space containing protons and electrons meets up with another plasma containing anti-protons and positrons. At what rest wavelengths would you expect to observe the spectral signatures of this collision?
Will both plasmas annihilate completely or only half of each plasma will annihilate? I know that when protons and antiprotons collide, they annihilate completely. But in this case, say, the protons surely can collide with the positrons instead of colliding with the anti-protons, right?
I think I need the "mass" to do the calculations. How can I figure out the total mass the the two plasmas? I don't know how many protons, positrons, etc., there are...
And I don't even know the speed of the protons, positrons, etc., how can I calculate the energy without the speed of the particles?
How many photons will be released? One? Two? Three? How can I know?
Any help of any kind is greatly appreciated! Thank you!:)
