Justifying that the gold nucleus is at rest in a Rutherford experiment
This is an example on the Rutherford Experiment from Young and Freedman's University Physics.
In the last paragraph of the solution the book states that it is valid to assume that the gold nucleus ...

Elastic scattering and conservation of spin
I am trying to understand conservation of spin in QED elastic scattering in these nice notes (VJ Martin, Particle Physics, Spring 2012, University of Edinburgh): https://www2.ph.ed.ac.uk/~vjm/Lectures/...

Rutherford scattering closest approach distance
Consider a particle 1 moving towards a particle 2 at rest. In class, my teacher said that in order to derive the minimum approach distance when the impact parameter ( b ) is 0, we had to use ...

Inconsistency in the $2\to 2$ kinematics
I must be confusing something horribly, because this should be very simple, but I am keep getting inconsistent results in the basic 2->2 scattering kinematics.
Let the process be $$a(p_1) + b(p_2) \...

Time of relativistic scattering
Consider a scattering collision between a relativistic electron and a Hydrogen atom, which is assumed to be in the ground state. Assume that the electron velocity is comparable to the speed of light $...

How is it possible to collide particles with specific momentum in microscopic scale?
Quantum theory says particles with almost specific momentum are spatially spreaded. (have relatively large spatial scales). Then how is possible to collide them very effectively in microscopic scale? (...

Photon collison with an atom
I'm currently studying atomic physics and have encountered a topic that I find challenging. My question is regarding the collision between a photon with an energy of, let's say, 12.20 eV and an atom. ...

Why is compton scattering inelastic?
With Compton scattering the total momentum and the total energy of the photon electron system is conserved, so it has to be ELASTIC Collision/Scattering.
But an argument is that just because the ...

Deep inelastic scattering remains
So I know that the process of deep inelastic scattering results in a collision of an electrons and protons in very high energies. However, I'm guessing that after the parton hadronizes, where would ...

What happens to protons AFTER deep inelastic scattering occurs?
As I understand in the deep inelastic scattering process, a collision of electron beams and protons occurs, resulting in a scattered electron. However, when the proton absorbs the virtual photon ...

Can I neglect rotation (angular inertia) in inelastic collisions, in the overdamped approximation?
In an overdamped system, "inertia", is neglected. See e.g., When is "Inertia" Negligible?
Does this mean that in an completely inelastic collision, for example when two disks ...

On physical interpretation of Mandelstam variables
The accepted answer to this post gives a nice physical explanation of the Mandelstam variables.
The only problem is that each variable seems to make sense only within a specific channel. Take the $t$ ...

Point of no return with two nearly colliding black holes [duplicate]
Consider two black holes traveling near the speed of light towards each other. No rotation, charge or other complexities and they are of equal mass. They move at near the speed of light towards each ...

How does one use Fermi's Golden Rule to calculate two-body rate of collision for a 1-D Fermi gas?
I am trying to verify a simulation I made of a bunch of non-interacting fermions (except elastic collisions) in a harmonic potential by comparing the rate of collisions from my simulation by using a ...
