查询词典 neutrino

The neutrino was first postulated in 1930 by Wolfgang Pauli to preserve the conservation of energy, conservation of momentum, and conservation of angular momentum in beta decay—the decay of an atomic nucleus into a proton, an electron and an antineutrino.

中微子是1930年由沃尔夫冈泡利为了保持能量守恒，动量守恒和β衰变---一个原子核（那时还没有认识到是中子）衰变成一个质子、一个电子和一个反中微子的角动量守恒，。
