Operators for Angular Momentum and Spin
When the eigenstates for a mode, or modes, of motion in a given system form a simple sequence or ladder, these states may be interconverted by applying an operator that moves the system up or down the ladder. In Section 5.7, such operators were constructed for the states of a harmonic oscillator; in Section 5.11, step-up and step-down operators were formulated for the radial motion of a particle in a Coulombic field.
