[mesa-users] approx13

[Ken Shen]

One major difference is the presence and participation of neutrons and
protons.  Among other things, I'd like to show that they are indeed
important for a given regime and are not fully accounted for with just the
(a,p)(p,g) reactions in approx13.

I think the approx13.net I attached before works if the isotope list also
contains neut, prot, and h1.  But it would be good to figure out why the
network is wrong without them, even though those isotopes don't participate!
