The Variational Method and the Harmonic Oscillator,here are very few Schrodinger equations for which one can find solutions in the form of simple analytical functions. It is necessary to resort to approximate techniques. The most important of these is the variational method, which we will discuss in this chapter. Its use will be illustrated by apply作者: Ferritin 時間: 2025-3-22 10:40
Three-Dimensional Problems,rse have to confront several particles in three dimensions. In this chapter, we remove one restriction by considering three-dimensional one-particle problems.
