: Potential wells, barriers, and the Dirac delta function potential.
It is always best to purchase a copy of the book or borrow it from a library to support the author and the publisher. quantum mechanics problems and solutions by aruldhas pdf
While Aruldhas is excellent, no single resource is perfect. If you cannot find the PDF, or if you need more rigor, consider: : Potential wells, barriers, and the Dirac delta
The primary resource for quantum mechanics problems by G. Aruldhas is his book, Quantum Mechanics: 500 Problems with Solutions : Potential wells
This is the heart of the subject. Expect detailed solutions for: Free particles. Particles in a box (one-dimensional and three-dimensional).
