Abstract: A theory is developed for the interaction of an electromagnetic field with one-particle quantum-confined states of positron and electron in spherical nanovoids of metals and semiconductors. In the framework of dipole approximation it is shown that the oscillator forces and dipole moments for the transitions involving one-particle states in nanovoids are rather large, exceeding the corresponding typical parameters of bulk metal and semiconductor materials. It is established that giant optical absorption cross sections in the quasi-zero-dimensional systems to enable to use these nanosystems as new efficient absorbing nanomaterials for infra-red radiation.
