WebFeb 5, 2024 · Imagine a particle trapped in a one-dimensional well of length L. Inside the well there is no potential energy. However, the “right-hand wall” of the well (and the region beyond this wall) has a finite potential energy. This means that it is possible for the particle to escape the well if it had enough energy. http://ursula.chem.yale.edu/~batista/classes/vvv/FiniteSquareWell.pdf
