MolecularMan14 Posted October 10, 2004 Author Share Posted October 10, 2004 opposite directional spin on the particles or on the atoms? how would that affect the reaction? Link to comment Share on other sites More sharing options...
ydoaPs Posted October 10, 2004 Share Posted October 10, 2004 spin isn't really the rotation of the particle just like quarks colors aren't red, blue, ect. Link to comment Share on other sites More sharing options...
MolecularMan14 Posted October 10, 2004 Author Share Posted October 10, 2004 lol, true, but what spins? does the particle spin within the atom, or does the atom spin itself? and how does this affect the reaction between the matter and the anti-matter?

ydoaPs Posted October 10, 2004 Share Posted October 10, 2004 here is a link that describes what i am talking about http://www.newton.dep.anl.gov/askasci/phy00/phy00562.htm Link to comment Share on other sites More sharing options...
MolecularMan14 Posted October 10, 2004 Author Share Posted October 10, 2004 AHHH, ok; that clarifies a lot. Thanks Link to comment Share on other sites More sharing options...
serunato Posted October 11, 2004 Share Posted October 11, 2004 But wouldn't it have to be opposite in value to be anti, like spin up vs. spin down? Isn't that how protons and neutrons couple? I am really just looking at how electrons act, but they only are described to have spin because they have magnetic moment and that is described as a charge that is in motion. Or am I way off?

Protons and neutrons couple by the strong nuclear force. There is an energy dependence of nucleons on spin, but that is at least in part a consequence of the Pauli exclusion principle (e.g. in Tritium, the neutrons would have to have anti-aligned spins to be in the same energy level) Link to comment Share on other sites More sharing options...
Gilded Posted October 11, 2004 Share Posted October 11, 2004 "spin isn't really the rotation of the particle just like quarks colors aren't red, blue, ect." Well, we don't really know 100% sure that the particles don't rotate around. Actually, doesn't the spin actually suggest that they are rotating?

Spin is just intrinsic angular momentum. Link to comment Share on other sites More sharing options...
