When a particle decays and spits off some alpha radiation why doesnt it take with it some of the electrons from its parent particle? I would expect the electrons to "stick" to the helium nucleus and travel with it.
I am guessing it is a matter of moment. The alpha particle flys off at such speed the resting moment of the electrons may make it so they cant follow it... but considering that electrons arent at "rest" and that they have very very little mass I question myself on this answer.
@mur2501 The quantum realm has parallels to classical physics and moment and mass are all valid at the quantum level.
That said you may be right that the answer is a quantum one and wont work well at all with a classical analogy... but a lot of things at the quantum level do work well witha classical analogy, at least to a point.
This is Mur 
@freemo
That does is true, at the end all fancy things happening on the quantum physics scale are supposed to generalise to classical physics when scaled.
Also it looks like Alpha particles have a very small probability of knocking out host atom's electrons from it's innermost orbits. This leads to X-rays being seen emitted from the atom with the alpha particle.
@mur2501 That makes sense... and sheds some light on it.
Accelerating electrons consume energy (And emit photons), which can be an additive effect to momentum (meaning an electron is harder to get moving than its mass alone would suggest).
So it makes perfect sense that it happens once in a while and looses some energy (in the form of x-rays) in doing so.
@freemo
I think this is related to bremsstrahlung radiation, though that much more applies to repulsive charges.
@mur2501 No I cant see why it would, the electron's path isnt curving via a large scale magnetic field.
If would be a direct result of the electrons acceleration.. its the same mechanism that causes pretty much all light.
@freemo
isn't the acceleration changing though?
@mur2501 yes, and as it changes it will effect how many and what frequency of photons it emits.. faster acceleration means higher energy adn higher frequencies of photon.
@freemo
actually, I for once want to look at the chaos side of physics and particles. I think we miss alot of explanations there.
Especially cause we don't even know if chaos is real or not.
if chaos exists, then where does it originate?
chaos is where physics, and maths both collide into the same realm.
@freemo I can't remember a whole lot but I believe that this very question helped lead to the development of quantum mechanics. Ugh now I'm going to have to go read about it.
@brianvastag Perhaps... I thought it was the peizo electric effect that was the big start of it all.
@freemo At a quick guess, you're close, but it's energy, not moment. The nuclear decay processes are very short range and all the electrons know about it is via electromagnetism (since they don't participate in the strong interaction, the weak interaction is too short-range, and the electron's mass is too small for gravity to be important). If you want the electrons to leave their orbitals, you need to pump some energy into them. The less-negative electromagnetic potential energy from the reduced nuclear charge isn't necessarily enough for that to happen quickly - the atom just exists as a -2 ion for long enough that the alpha particle has time to escape.
I'm not a particle physicist; just trying piece together what I remember from undergrad physics.
That adds up with all the speculation and info... It just escapes way too fast for the electron to have a chance to follow it.. though apparently it does happen rarely and when it does produces X-rays.. which adds up.
For me your mas.to account is actually showing as forwarding to calkey, not the other way around.
the child porn and a few other incidents with your server were in the past. It wasnt an issue for qoto.org as we never noticed it on our end (if we had we would have blocked) but since we didnt we never blocked.
Calkey has us blocked because they got blocked once and then tried to blame us for "tricking" them so they blocked us.. its a long story.
In the end they wound up on the fediblock.lgbt list and then shortly after that they changed their server name to circumvent the list.
You can still see the old block list though: https://fediblock.lgbt/
It doesn’t for the same reasons a bullet won’t be wet after you shoot it through a watermelon. The electrons would need to be sped up to high velocities to match the alpha, but there is very little time for them to interact with the alpha before it leaves the atom. They -will- get knocked around though, causing x rays or shake-off electrons.
@ThreeSigma Thanks, this tracks.
@freemo aren't you trying to apply classical physics to the quantum realm here?
