Orbital Angular Momentum
摘要
In Chaps. 5 to 7 , we have applied quantum mechanics to one-dimensional problems. Most physical applications of quantum mechanics, however, are three-dimensional problems. Before starting their study in the following chapters, we will define an important operator and study its properties with respect to quantisation. This operator is the quantum extension of a classical quantity, the orbital angular momentum,Orbital angular momentum and it is obtained from the correspondence principle.
