Finite square quantum well - depth

Click For Summary
SUMMARY

The discussion focuses on determining the conditions for the depth of a finite square quantum well that allows for two even and one odd bound state energy eigenstates. The established range for the well depth is given as h²/8mL² < Vdepth of well < 9h²/8mL². This range ensures that no additional bound state solutions exist beyond the specified eigenstates.
