why Nuclear Physics cannot be entirelly correct

[AdMan]

What produces the proton's magnetic moment ?

(Guys, his posts are in a larger font than normal. He must have a valid point!)

 

[Horatius]

I am primarily a nuclear experimentalist nowadays, but I've published in nucl-th, nucl-ex, hep-ex, hep-ph, and astro-ph. The spin of the nucleon is its angular momentum. This is (not coincidentally) oriented in the same direction as its magnetic moment, but they are different things. The spin is not "electromagnetic" in any way, shape, or form---and nor is it "strong" or "weak" or anything else. A spin-up particle simply has a different wavefunction than a spin-down particle, and that difference needs to go into any particle-interaction calculation you could possibly do.

Did you bother to notice, for example, that the gluon is spin-1? Yet it has no charge, no magnetic moment, etc.

Did you bother to notice that the W-boson is spin-1? It interacts with neutrinos (not electromagnetically) and it obviously cares about the neutrino spin.

Pwned!

What is the magnitude of the spin-orbit interaction in Mayer-Jensen theory?

I suspect the "Mayer-Jensen theory" is just the nuclear shell model developed by Maria Goeppert-Mayer and J. Hans D. Jensen for which they got their Nobel Prize.
I would say that the magnitude of the spin-orbit interaction is really complex given the complexity of the (simpler) atomic spin-orbut interaction.

The answer is of course: it depends, e.g. on l.

Why do you want to know it, pedrone, and for what state?

 

[nvidiot]

And why does this particular piece of nuclear physics prove whatever it is you're talking about Pedrone? What are you trying to tell everyone?

What evidence do you have that nuclear physics is wrong?

 

[pedrone]

The spin is not "electromagnetic" in any way,

I did not say that the spin is electromagnetic.

I said that the spin-interaction is electromagnetic, which is totally different.

So, the spin-interaction of a proton is electromagnetic.


Now, please respond: what produces the magnetic moment of a proton ?

 

[pedrone]

What evidence do you have that nuclear physics is wrong?

Ask it to Ben M,
since he does not know to explain us why the spin-interaction influences the proton-neutron interaction,
and so he cannot explain why Nuclear Physics is disproved by some experiments

YOU made a claim. Which you have yet to back with any evidence, maths or expermental results, let alone even narrowed that claim beyond anything but "nuclear physics is wrong".

So I'm asking YOU:

What is wrong with nuclear physics?

There is no such thing as "spin-interaction".
There is the spin-orbit interaction which is a quantum mechanical effect causing a shift in the energy levels of bound particles. Those energy levels are "electromagnetic" only in the sense that an electron or nucleon changes levels by emitting or absorbing light. They are not caused by electromagnetism.

But it doesn't have a lot of words in all-caps, or a lot of exclamation points, so how can we be sure?

BLAH BLAH BLAH BLAH

I will not waste my time with lay men

Let's wait the response by Ben M.

So, Ben,
please tell us: what produces the magnetic moment of the proton ?

Everbody is waiting your response !!!!!

 

[pedrone]

Are You A Kosher Butcher?

Who knows?

He also proved that Nuclear Physics is wrong ?

Forgive my impertinence, but what are your credentials?

Ask it to Ben M,

He does not have to because it is basic nuclear physics. Or even reading comprehension !
spin-orbit interaction

In quantum physics, the spin-orbit interaction (also called spin-orbit effect or spin-orbit coupling) is any interaction of a particle's spin with its motion. The first and best known example of this is that spin-orbit interaction causes shifts in an electron's atomic energy levels due to electromagnetic interaction between the electron's spin and the nucleus's magnetic field. This is detectable as a splitting of spectral lines. A similar effect, due to the relationship between angular momentum and the strong nuclear force, occurs for protons and neutrons moving inside the nucleus, leading to a shift in their energy levels in the nucleus shell model.

It does not "influence the proton-neutron interaction". It influences the energy levels that are possible in a system.

 

[dasmiller]

I did not say that the spin is electromagnetic.

I hope you can understand how we might have interpreted

2- The spin of nucleons is electromagnetic,

to mean that the spin is electromagnetic.

Oh my God !!!
A nuclear physicist that knows nothing about basic nuclear physics

In quantum physics, the spin-orbit interaction (also called spin-orbit effect or spin-orbit coupling) is any interaction of a particle's spin with its motion. The first and best known example of this is that spin-orbit interaction causes shifts in an electron's atomic energy levels due to electromagnetic interaction between the electron's spin and the nucleus's magnetic field.

That's why I dont want to waste my time with lay man
Such spin-orbit interaction is regarding the ATOM, which has nothing with the NUCLEUS


Guys,
I understand that you want to help Ben M.

Unfortunatelly, even God cannot help him (unless God changes the laws of Nuclear Physics)

So you just waste other people's time?

please tell us: what produces the magnetic moment of the proton ?

The sum of the intrinsic magnetons (mostly) and orbital angular momenta (less) of the consitutent and sea quarks.

Everbody is waiting your response !!!!!

No they're not. Normal people who want to know that fact would go look it up. Why didn't you?

 

[dasmiller]

BLAH BLAH BLAH BLAH
I will not waste my time with lay men

I hope you can understand why we might have interpreted

I will give here an example so that to be understood by a lay man.

in the OP to mean that you were interested in some interaction with laymen.

 

[Ziggurat]

I did not say that the spin is electromagnetic.

Um... you do know that people can check that, don't you?

2- The spin of nucleons is electromagnetic

Oops.

Is this sum of the intrinsic magnetons produced by their spin ?

Is a spin of the proton such orbital angular moment of the quarks ?
