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 ...

Time of collision of two particles arriving with Planck time difference
Suppose two particles, $A$ and $B$, arrive at a certain point $P$. After arriving, whichever particle arrives first stops until the other particle arrives later and collides with it.
Now, let's say ...

Is the collision in LHC quantum mechanically so we cannot predict the trajectory?
I'm puzzled as always. In the LHC 2 streams of particles are accelerated in opposite direction and allowed to smash against each other in a controlled accident, then is it classical or quantum ...

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 $...

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 can a beam of electron and not scatter with a proton to form a H atom? [duplicate]
*Consider aimimg a beam of free electrons towards an isolated free proton . When they scatter, an electron and a protons cannot combine
to produce a H-atom because
A) Energy Conservation B)without ...

How does dual nature of matter affect collision at the quantum level?
I have a question suppose having two fundamental particles collide which each other at the quantum scale , then what will the collision behave as
Will the particle nature be dominant and make sure to ...

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 ...

When we say atom collides with another atom, is it particles collision or wavefunction interaction?
I just want to know what is happening in real time when two atoms is setup to collide together, is it really like a billiard where a ball is hitting onto another ball so in this case the two atoms ...

When an electron hits a fluorescent screen mounted on a spring, why can't we get both position and momentum?
From the Heisenberg's Uncertainty Principle for position and momentum we know that, $x$ and $p$ of a particle cannot be measured simultaneously with arbitrary accuracy.
$$\Delta x \Delta p \geq \hbar/...

Can a X-ray photon increase its frequency after scattering of a nucleus?
Can a X-ray photon increase its frequency after scattering of a nucleus? Let say nucleons are oscilating inside a nucleus due to interaction between residual SNF and Coloumb force... Can this ...

When does a collision become classical?
I was thinking (after misinterpreting and answering another question) about collisions on the atomic scale. I know it's impossible to visualize, but I did.
For example the collision between an ...

How are we able to study Quantum phenomena in Particle physics using relativitity?
When we look at at a relativistic collision like compton scattering or decay of the Higgs particle, we treat the colliding particles literally as particles following a definite trajectory and ...
