Quantum Mechanics, Volume 2 by L.I. Schiff, translated by Ken Inoue This is a considerably old book. The cover has damage such as scratches, but the book itself is very clean and in good condition, and doesn't show much of the aging typical of used books. Instant purchase OK. Feel free to comment if you have any questions. I will reply to you even if I'm late. Many other items are also on sale. #QuantumMechanics #Physics #UsedBooks
