Wait, @ACuriousMind
What are the requirements for electron capture? Doesn't it have to do with binding energy?

@0celo7 why not just make him a Reaper too while you're at it

@SirCumference Like all such nuclear reactions, it can in principle happen when the resulting state has less mass (so it has to do with the binding energies, yes)

he's already got a lot of hats and its not like the aliens couldnt do data collecting before him

@user507974 I'm not convinced he wasn't indoctrinated the whole time.
Sir Cumference
Sir Cumference
@ACuriousMind So what would allow it to happen? It can't happen on all atoms and isotopes, can it?

@0celo7 did you end up seeing the video about indoctrination theory
i just dont want to post major spoilers in the comment area
for folks who havent played

@user507974 No.

@SirCumference Well, you have to inspect the daughter nuclid that would be created by electron capture, and figure out whether it has less mass than the parent.

I need to do homework now, actually.
But I must read @ACuriousMind 's article.
@ACuriousMind How much longer is this?
ACuriousMind
ACuriousMind
@0celo7 35 posts until now, I think 46 are planned

Sir Cumference
@ACuriousMind All right, and if it does?

@user507974 I think we've spoiled pretty much the entire game scattered somewhere in this chat
@SirCumference Then electron capture is in principle an allowed mode of decay
Sir Cumference
Sir Cumference
What would happen to the mass?
ACuriousMind
ACuriousMind
@SirCumference It becomes energy (in the form of the daughter nuclid being in an excited state and the neutrino getting kinetic energy)
$E=mc^2$ and all that.

OOOOH

@ACuriousMind Ok, I'd better stop reading. Time to do algebra homework.
Sir Cumference
Sir Cumference
Well, can I have an example of an isotope like that? When would the daughter have less mass than the parent?

@SirCumference Negative mass isotopes.

@SirCumference Wikipedia has some examples
