Homework Statement
The potential energy of a particle is defined by the piecewise function:
V(x) = infinity if x<0
V(x) = -V0 if 0<x<b
V(x) = 0 if x>b
So it's like a square well with one side being infinite. I need to find the condition on V0 and b so that no bound stationary states exist, then for there to be exactly three stationary states.
Homework Equations
Uh.. not sure. For a regular square well, I have that if V0 > 0 there is at least one stationary state. So for there to be none, V0 has to be less than zero? But this isn't quite the same as a square well.
The Attempt at a Solution
See above. I also know that each stationary state must have a node at x=0. I just don't know how to put all this together..
