Chapter 4 Time–Independent Schrödinger Equation
... The finite potential well in one dimension always has a bound state, but this is not generally the case for all dimensions. The 3–dimensional Schrödinger equation does not automatically allow for a bound state in such a problem. Though the equation can be rewritten in terms of the radius r, and thu ...

01 introduction to quantum physics
... No solutions exist for any energies “in-between.” This is in sharp contrast with classical dynamics where there is a continuum of allowed energy values. The equation also determines that other quantities such as angular momentum and spin have similar discrete values. However solutions may also inclu ...
