I know, but it's a rather silly title!

In the examples you've shown, the ones denoted by an energy decay rapidly via neutron emission. This happens on timescales on the order of femtoseconds or less. The value for the energy comes out of the uncertainty relationship. Effectively "Energy * time < h-bar", where 'h-bar' is Planck's...

I'm wondering what "Thing" is and why we are even concerned about "It's Law".

Rock on.

The potential energy between two nucleons obeys the Yukawa potential. At small separation distances the potential energy is positive, and there is a strong repulsive force between the two nucleons. At larger distances, the potential energy is negative, and there is an attractive force. You can...

Uhhh...ummm...hmmmm?

The proton is considered stable on time scales much greater than the age of the universe. Experiments like the one mentioned above establish that proton decay (if it happens) is extremely rare. The experiment referred to was carried out at the Super-Kamiokande water detector in Japan (also used...

That's impulse, or change in momentum.

As long as Purdue doesn't go to the extremes the University of Utah did in 1994, I'll be happy.

For I = 1, the allowed values of the isospin projection I3 are -1,0,1.

I'm referring to experiments like SPS, RHIC, or the upcoming ALICE. The heavy-ion experiments.

Anyone who comes through here involved in high-energy nuclear physics? Just wondering if there are other people out there who work in the field.

I've been there to visit. I know more about RHIC though. Both are cool places.

OK, then we are not talking semantics. You are using your own definitions. Until it starts showing up in refereed physics journals, I think I will stick to the usual vernacular.

Close proximity? The nuclei smash into each other. I would call that a collision. The impact parameter may change, but the difference between colliding and not colliding is substantial. If you want to look at it in terms of Feynman diagrams where the partons don't come directly into...
