Abstract:
The angular momentum structure and energy structure of the coherent state of a 20 isotropic harmonic oscillator were investigated. Calculations showed that the average values of angular momentum and energy (except the zero-point energy) of this nonspreading 20 wavepacket are identical to those of the corresponding classical oscillator moving along a circular or an elliptic orbit.
