Heavy element production in MM

MV, I tried a search of the paper you referenced about the spectral data of H-bomb fallout. There is nothing on line near that topic so can you post a link? thanks

The electron cannot be confined within the volume of the proton.

The uncertainty principle is still around after some 80 years of "wrangling". Apparently many people accept it as a viable property of matter and no other model has been proferred which better describes experimental results.

The position and momentum of a particle are related through Planck's constant. If you determine the position of a particle with, say, the precision required to place it within the proton, it's momentum will necessarily be very high. Hence, it goes flying out of the proton.

Get it?

The electron can be inside the proton but it can't stay there for long. If you detected it as staying a long time, there is a corresponding amount of energy it must possess and this requires that it fly outta' there.

<br />Well, I guess it's true then.

Heisenberg, Bohr, Dirac, DeBroglie, Pauli, Schrodinger, Feynman, Gell-Man, etc. were just a bunch of idiots. ;o)

It's not OUR knowledge of the position and momentum of an electron that counts. It's the electron's "sense" of where and what it is that determines what it will do. Apparently, since it percieves no reference frame (on the scale of its own dimensions), it can't stay in a smaller volume either. Which means, it can't reside within the proton which is much smaller, i.e. like a telescope looking for details on Mars, it can't "resolve" the image of the proton and thus cannot locate it with sufficient precision and thus ... "go there".

Something like that is closer to the correct answer.

I see what you mean. But if we can claim that the proton is much smaller than the electron, why do we invent uncertainty to conclude that the electron will not go there? I fail to see what uncertainty has anything to do with this. The proton has a certain dimension and so does the electron, so if the electron is larger, it will not go into the proton for trivial reasons. Please fill me in on this one since it is clear I don't get it. []

Here's very nice explanation of the principle:

123,

Thanks for the link.

"it is no longer valid to consider a particle like a hard sphere, because the smaller the dimension, the more wave-like it becomes. It no longer makes sense to say that you have precisely determined both the position and momentum of such a particle."

So, from what I gather, uncertainty says that measuring forms below certain scales shows that these forms are not point-like but distributed entities instead. Simply put, suppose we are on a boat and look at the waves from a distance, then these waves look like entities themselves, but if we come close enough, we are likely just to see water and not those waves. No?

Jim, the data is hardbound at NCSU, I don't think there is any e-copies. Call them in Raleigh.
