Determine scattering amplitude for atomic charge which is "spread" as wavefunction
Homework Statement
Derive the scattering amplitude and differential cross section for Rutherford scattering (done this). Now rederive the same quantities for the atomic charge which is "spread" with the...
Just came up with a new thought, I could create a situation such that the electron and positron are approaching each other in such a manner that initial p=0. This would allow the dismissal of the "at rest" presumption. Thoughts?
Homework Statement
The problem is listed as follows: Show that conservation of energy and momentum require at least two gamma rays to e emitted in the annihilation of an electron by a positron.
Homework Equations
p(initial) = p(final)
E(initial) = E(final)
Total rest mass = 1.0218...
Hey everyone,
I'm currently taking a thermal physics course and have been assigned a research paper about the thermodynamically arguable aspects of experimentally observed properties of the 3He superfluid. I have been searching for many different sources but have only found a few worthwhile...
Homework Statement
Hey everyone. I've been trying to figure out these two problems for a few hours now to no luck. I really have no idea where to start. Hopefully, someone can help me out.
1) a) How much time is needed to measure the kinetic energy of an electron whose speed is 10.0 m/s with...
