[题目]
The tempreature of the surface of a certain star is 7000K. Most hydrogen
atoms at the surface of the star are in the electronic ground state.
What is the approximate fraction of the hydrogen atoms that are in the
frist excited state? The energy of the first excited state above the
ground state is (-13.6/4 eV) - (-13.6 eV) = 10.2eV = 1.632 * 10^-18 J
(Ignore the fact that there may be several excited states with the same
energies, for example, the 2s and 2p states in hydrogen.)
[瓶颈] (写写自己的想法，方便大家为你解答)
这题是要用Boltzmann distribution, P(E) = A * Omega(E) * e^(-E/Kb*T)吗?
A为常数 Kb是波资曼常数
如果是那要怎麽求 A and Omega(E)?
请各位大大解惑!
