  • A model for cylindrical nanoporosity based on single positron annihilation
    Felix, MV; Castaneda-Contreras, J; Morones, R; Castano, VM; Rodríguez-Rojas, RA (2005)
    A semiempirical positron stationary Quantum Model was developed to study nanoporosity in solid porous materials, such as silica gels. The cylindrical well potential is considered and its geometric parameters are related ...
  • Nanoporosity as quantum positron traps
    Felix, MV; Castaneda-Contreras, J; Morones, R; Castano, VM; Rodríguez-Rojas, RA (2005)
    Two-semiempirical positron stationary quantum models are developed for the study of nanoporosity in a wide range of solid porous materials. The cubic and conic well potentials are considered and their geometric parameters ...
