Registration Date 13-02-2012 Organization Zhytomyr State University named after Ivan Franko popup.description2 The theory of positronium and positron states in the spherical nanopores, which are situated in the nanocrystalline metals, is developed. The energy spectrum and positronium bonding strengh in the nanopores and their dependence upon the nanopores' radius are theoretically discovered. The gigantic value of the oscillators' strength of the junctions and cuts of the light absorption in the metals nanopores is established. The possibility of the experimental research of the positronium and positron states in the nanopores is shown. The method of the optical spectroscopic determination of nanosystems' parametres, which is based on the comparison of the experimental spectra of the positronium absorption with the spectra theoretical dependences upon the nanopores' radius, is proposed.
