But only a small part of those ion beams take part in the reaction. At 100KeV, 10^11 ions occupy about ~1 cm^3 at 1atm. Compressed to lead density, isotermicaly, they would occupy around 100cubic micometers. So, those other ions must be extremely cold and outside the plasmoid or in the periphery. It seems then that proportionally, He 3 disrupts the core of the reaction.
