A nuclear reaction for deuterium-deuterium fusion is: D + D --> He3 + n
(d=deuterium n=neutron, He3=Helium-3). However I thought that Helium-4 is a more
stable isotope than helium-3, and hence would have predicted that: D + D --> He4
+ photon, would have been more likely. Why is this not so? Thank you.
