Homework Statement
Use Saha-Boltzmann statistics to get an idea of the relative number densities of H, H+, H−, and H(n = 3).
Gather information from Gray’s book concerning the partition functions (hint: with its two electrons H−
is He-like; H+ is a naked proton, so U(p) = 1), the electron pressure, and so on. Assume T = 5772 K
(S 0 = 1, as Gray labels it in the relevant plots) and solar surface gravity. Take care with the units!
· What do you learn from comparing N(H−) and N(H, n = 3)?
Relevant Equations
The Saha equation N_i+1/N_i
for i:s energy levels.
When I am using the Saha equation, how i am suppose to know the electron pressure?
Which are required to calculate the ration?
Since: P_e = n_ekT (electron pressure and n_e is related to each other, but n_e is also unknown based on my understanding).

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
