Very odd. How could they then reach any fusion if they have a hundredth of the needed velocity (50 km/s instead of 5000 km/s)? If they still detected alpha part

Very odd. How could they then reach any fusion if they have a hundredth of the needed velocity (50 km/s instead of 5000 km/s)? If they still detected alpha particles... I get 1600 km/s from a naive calculation, still a factor of 30 off: https://www.wolframalpha.com/input?i=sqrt%282*150+kev+%2F+%28boron+atomic+mass%29%29 https://www.wolframalpha.com/input?i=sqrt%282*150+kev+%2F+%2...
