So which gammas are emitted in the first case, and what would you expect if the reaction were 7-Li + H* --> 8-Be --> 2 4-He? ...and how do you know that the first reaction isn't really:- 7-Li + D* --> 8Li (neutron transfer) + p (wanders off) --> 8-Be --> 2 4-He, making use of trace D in the H? Does the reaction rate change if you incrementally add D to the H? > >To learn about this use. >https://www-nds.iaea.org/relnsd/vcharthtml/VChartHTML.html > >Most of the time the A+D* reaction is followed by a beta+ decay.
