Homework Statement
A hydrogen‑like ion of calcium emits a photon with energy E = 756 eV. What transition was involved?
Homework Equations
The energy equation: E=Z^2*E_R*(1/n^2-1/n'^2)
The Attempt at a Solution
First, Z=20 for a calcium ion, and E_R is the Rydberg energy 13.6 eV. Then I plugged everything in assuming that the electron which emits the photon goes back to the ground state, i.e. n=1.
However, I get n' ≈ 1.07, which does not seem sensible to me.
Any ideas or suggestions, please? Much appreciated.
Note: How do you write down the equations in a neat format on the forums? I'm a newbie so please go easy on me!
