- Well, to me the situation is not analogous to chemistry, because in
- chemical systems the interation is always present between physically
- nearby reactants (being electrical in nature), while in nuclear interactions
- the interaction is not always present (being the short range strong
- force) between physically nearby reactant. So, if you toss in the gammas,
- the d-d-gamma dont all see eachother anyway.
-
- Still, even when one thinks about it in a more proper intuitive way,
- it seems a bit odd (please correct my intuition....): in my mind,
- in the d + d -> He + g, the two d nuclei slam together and start
- vibrating, and the vibration shakes off a gamma of the same frequency.
-
- if you add the gamma back to a bunch of d's, so what? it may shake
- individual d nuclei a bit, but it bounces off because its not
- at a resonant frequency and in any event it doesn't seem to
- encourage the d's to get close together.
