How does QED describe the electromagnetic scattering between two neutral fermions?
Fermions with no electric charge may carry magnetic moments e.g., the neutron. Since particles with magnetic magnetic moments interact, they're expected to scatter off each other electromagnetically. ...

Refractive index of EM waves travelling though a gas of neutral particles
From what I have read and seen online. The explanation of why there is a net reduction in the speed of EM waves through a medium is due to the interference with the oscillating EM fields produced by ...

Nuclear fusion reactors and neutrons
The majority of energy produced by nuclear fusion is harnessed by neutrons or protons that split out from the product.
Given the dominant fusion method today is Deuterium + Tritium which produces He ...

Neutron Spin and external magnetic field
I know as a fact that neutrons have spin 1/2, as spin is an angular momentum it should couple with an external magnetic field, so that means that the neutron is interacting with B and has q=0, so iḿ ...

How, exactly, does an electron scatter off of a neutron?
I thought about this recently because of news articles discussing the measurements of the 'neutron skin' of large nuclei....
Is it due to the fact that both have a negative magnetic moment?
Or to ...

Is there any conversion mechanism of neutron radiation into electromagnetic radiation?
Charged radiation such as beta, alpha or even stray protons and nuclei as they are charged can loose their energy as photons. Can neutrons do this as well, even if they do not have any electric charge ...

How can the neutron have any 'electric polarizability'?
If a neutron has no identifiable electric charge or polarization, as far as anybody has been able to determine, how can it have a value for 'electric polarizability'?
Wikipedia has a value listed that ...

Quantum mechanics. Scattering from step potential barrier of magnetic field
I am having trouble to think how to solve the following problem:
The plane $x=0$ separates two parts of space: when $x>0$ there is homogeneous magnetic field, which induction vector $B_x=B_y=0$, ...

'Forces' enacted by hot neutrons in fusion bomb - Pauli exclusion
Are Pauli exclusion 'forces' on a neutron 100% electromagnetic (Lennard-Jones seems more acute relationship compared to electrostatic force)
If so does that neutrons have two forces between them - '...

How do we know neutrons have no charge?
We observe that protons are positively charged, and that neutrons are strongly attracted to them, much as we would expect of oppositely charged particles. We then describe that attraction as non-...

Creating isotopes by shooting neutrons into an unstable nucleus [closed]
I've been doing a lot of amateur research lately (youtube videos) on particle physics and find it all really interesting. I'm also a crazy alien conspiracy theorist who believes in the whole "Bob ...

What is the true nature of neutrons? [closed]
I have been spending time thinking about atoms with an open mind. In general, I am trying to think of atomic and molecular physics in terms of pure magnetism. I am going to explain my train of thought ...

What is a neutron's polarizability?
It is undergraduate textbook level knowledge that atoms are polarizable – that is, they become electric dipoles in electric fields due to the deformation of the electron wave function(s). ...

How does the divergence of the B field is zero imply that neutrons only "see" spin components perpendicular to the scattering vector?
The following statement is made in a text with no further explanation:
"...a direct consequence of Maxwell's Law $\nabla \cdot B = 0$ that implies $B(q)$ has no component parallel to $q.$ This means ...
