Finite square well potential question
For a finite one-dimensional square potential well if a proton is bound, how many bound energy states are there?
If m = 1.67*10^(-27) kg a = 2.0fm and the depth of the well is 40MeV.
Now I know the energy levels are
En = (n^2 * h^2) /(8ma^2) = (n^2*pi*2)/4 * (2hbar^2)/(ma^2)
but I am unsure as to how to find the number of the allowed energy states. Any help would be greatly appreciated.

Determine n belonging to the maximum magnitude of energy less then 40 MeV. But take care: the formula you cited refers to infinite potential wells. Here the potential well is of finite depth.
