- The problem is that DD doesn't go this way. There are two branches:
- D + D --> He^3 + n + 3.27 MeV
- --> T + p + 4.03 MeV
- with equal probability. Most energy from D + D comes from the secondary
- reactions, which have much higher cross-sections:
- He^3 + D --> alpha + p + 18.3 MeV
- T + D --> alpha + n + 17.6 MeV
- In each case, the energy is divided such that C/M momentum is zero.
-
- I think D + D --> alpha violates some quantum transition rules.
