The temperatures, time, and densities were sufficient to combine a substantial fraction of the deuterium nuclei to form helium-4 but insufficient to carry the process further using helium-4 in the next fusion step.
Teploty, čas a hustoty boli dostatočné na to, aby podstatná časť deutéria vytvorila hélium-4, ale nedostatočné na použitie hélia-4 v ďalšom kroku fúzie.
