Approximation Methods,nalytic and numerical solutions take on great importance. Numerical solutions are the topic of Chap.?.; this chapter deals with approximate analytic techniques. Three methods are explored. These are (1) The Wentzel-Kramers-Brillouin (WKB) method for estimating the energy of the .’th energy level of

A Few Results from Time-Dependent Quantum Mechanics: Transition Rates and Probabilities,ich the system will transit between given quantum states; (2) How rules which dictate what transitions are in principle possible can be derived; and (3) How to estimate the probability that a system will be in a given quantum state following a transition. The intent here is not rigorous analyses, bu

Foundations,at classical concepts of mechanics and electromagnetism would need to be modified to understand atomic structure, particularly the existence of discrete energy states and the wavelike behavior of particles on atomic scales. This work set the stage for the development of quantum mechanics proper in 1925–26.

This chapter also gathers together some theorems regarding wavefunctions which will be useful in later chapters: the orthogonality theorem, the superposition theorem, the virial theorem, and the behavior of time-dependent wave “packets” constructed from “superposition states”.
