- Look, the fusion scenario we are working on is the D + T, which has the
- highest cross section. We normally work only with D, since T is quite
- difficult (more expensive) to handle safely. The small DD fusion rate
- can be and has been measured in many tokamaks. Fusion neutrons from
- D + T were measured directly in the JET DT shots; the "fusion power"
- (which was *not* recovered in any usable form) of 1+ MW was calculated
- from the production rate of these neutrons.
-
- I'm not surprised that no-one has seen *cold* fusion with T, since this
- is illusory in general.
-
- Jim Carr answered to the effect that D + D --> alpha + gamma does indeed
- violate selection rules; that's why the cross-section was so small that
- the NRL "blue book" made no mention of it.
-
- Rolfe Petschek gave the quantum details. Both posts confirmed my suspicion.
