摘要：
We analyze resonant phenomena in finite quantum wells involving intersubband transitions from the ground state into the continuum spectrum. The momentum matrix element is shown to exhibit oscillatory behavior due to the presence of virtual levels. Estimates of the momentum matrix element based on the infinite quantum-well approximation are found to be inaccurate.
