It makes a lot of sense when we look at it energetically, because if we think about a 1 s core electron, that's going to be held really, really tightly to the nucleus.

从能量的观点来看这是非常合理的，因为如果我们考虑一下，1,s，芯电子，它会被原子核束缚得非常非常紧。

Electron-neutrinos are created in the thermonuclear reactions at the solar core.

BBC: SNO, SNO

One explanation for the solar-neutrino deficit (only a third of the predicted number have been detected) is that electron-neutrinos produced by nuclear-fusion reactions in the sun's core mutate into the other two types, which are harder to detect.

ECONOMIST: The news that neutrinos have mass is both good and bad
