Extracting electron wave functions from experiments
In nuclear and nucleon physics it’s quite standard to extract electromagnetic form factors – which are the Fourier transforms of charge and current distributions – from elastic electron-nucleon or ...

Could the scattering of molecules lead to bond compression?
Suppose you were to send a fast moving binary molecule (such as H-H) at another large target atom A such that the molecule is aligned with the direction of its travel towards the target atom. In other ...

Blue color scattering [duplicate]
I'm trying to understand, in terms of cross sections, why is the sky blue? Intuitively, blue has a smaller wavelength than the rest of the colors so it can "see" the internal structure of ...

Valence electron energy and scattering angles in Compton scattering
The Compton scattering of the X-ray from electron is depicted below with x-axis being the dir. of the incident photon:
Its wavelength shift amounts to:
$$ \lambda_f - \lambda_i = \frac{h}{m_ec}(1-\...

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 $...

Why is a singlet state potential greater than triplet state potential in the Feshbach resonance experiment?
I googled the Feshbach resonance in the Wikipedia and I have some problems. In German Wikipedia, they consider Li-6 molecule as an example.
For these two different spin configurations(singlet and ...

Rutherford's experiment
I have read everywhere that the gold foil experiment performed by Rutherford was done hoping that the alpha particles face only a little deflection/no deflection however this doesn't sit right with me,...

Does Thomson and Rayleigh Scattering cause any change in rotational and vibrational energy of an electron or atom?
We know from molecular spectroscopy that incoming light on a molecule can change a molecule's rotational, vibrational and electronic energy levels.
If the incoming light is,
on the far-infrared and ...

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 the alpha particle beam in the Rutherford experiment not affected by the electrons?
The force exerted by the nucleus on the alpha particles is electrostatic in nature. So, why does mass has an effect? How do we conclude that the electrons don't effect the alpha particles from the ...

Thomson Scattering - Wikipedia is vague
From Wikipedia, I'm copying two things:
It is the low-energy limit of Compton scattering: the particle's kinetic energy and photon frequency do not change as a result of the scattering.
In the low-...

What if atom receives energy higher than $\Delta_1$ but lower than$\Delta_2$? [duplicate]
Considering an atom at ground state 0.
To be excited to state 1, it needs to get, as understand $E_e = E_0 - E_1$.
What if, atom at $E_0$ interacts with photon, which energy is higher than $E_0 - E_1$,...

In bremsstrahlung radiation, why does the electron decelerate when it is deflected by the nucleus?
The nucleus would attract the electron so its kinetic energy should increase right? If this is the case where is the energy for the radiation coming from?

When light is scattered, How do particles in sky decide which frequency to vibrate at?
I understand that when electromagnetic waves from sun hit/interact with the particles(charges) in the sky, the particles also oscillate with the same frequency of sunlight and hence radiate(scatter) ...
