neutrino
nooh tree noh
- n an elementary particle with zero charge and zero mass
- Unless a neutrino scores a direct hit on an atomic nucleus, it leaves no hint of its passage.
- The neutrino would neatly explain a tiny energy imbalance in certain nuclear reactions, but it would also be so ethereal that the average neutrino could zip through a trillion-mile .
- For 20 years nuclear physicists have used neutrinos (small, uncharged particles) in their calculations.
