Hi Chuck
So long as the leak was small, there would be close to a vacuum inside.
So, as Chuck says much less than one atm.
If it was a large leak, it would be atmophere with no detectable He.

Just a thought, but while He does leak out of
just about everything,
unless something is leaking in I suspect its still He around 1 atm.
It would seem that the partial pressure of He in the atmosphere is
much less than one atm, no? So, barring inward leaks, would not a
lot less than one atm. of He would be left inside?
Perhaps I've disremembered Dalton's Law or just hallucinated (seems
to happen more and more as I grow older) that I endured high school
physics?
