Thomson Scattering when low intensity light meets an orbital electron

Can you explain to me the reason why Thomson Scattering can not explain what happens when light meets an electron at low intensity, and what does that have to do with light being a wave or particle or ...

How does a photon interact with EM field of a nucleus thus exchange momentum and recoil the nucleus when pair production happens? [duplicate]

The photon must be near a nucleus in order to satisfy conservation of momentum, as an electron–positron pair produced in free space cannot satisfy conservation of both energy and momentum.[4] Because ...

Why take into account deceleration radiation only, but not acceleration radiation when Bremsstrahlung happens?

Why only take into account deceleration radiation rather than the radiation caused by acceleration when going tangent towards the nucleus and acceleration caused by the change in direction when flyby ...

What is the lowermost energy a photon can be emitted by hyperfine transitions?

The 21 centimeter Hydrogen line comes from the hyperfine transition from its one electron, which leads to a photon with the energy of $2.24\times10^{-25}$ joules being emitted. Can lower energy levels ...

To which extent is the treatment of nuclear multipole radiation by the means of a classical electromagnetic field valid?

In the treatment of nuclear multipole radiation, for example in the context of nuclear gamma decay, it is standard, at least at the elementary level, to formalize the electromagnetic radiation as a ...
