Doing it right

Sensawunda for physics geeks

But still. While I was doing a bit of research for a filk song, I learned that the list of known isotopes of hydrogen now goes up to 7H, i.e. 1 proton, 6 neutrons. The known isotopes of helium now go up to 10He, i.e. 2 protons, 8 neutrons. All of them are unstable, other than the lightest two for each element, of course. But the half-life of 8He is a remarkably-long 119 ms, and that of 6He is a stunning 806 ms.
Weird.
