    Abstract : This thesis presents a nonadiabatic (4-body) description of the hydrogen-antihydrogen system at a nonrelativistic level. The properties of the system, the rearrangement processes and the possible existence of resonance states are investigated by using a variational method for coupled arrangement channels, the Gaussian Expansion Method, and the stabilization method.

  4. 2. MATTER-ANTIMATTER INTERACTIONS : The hydrogen-antihydrogen system and antiproton-matter interactions

    Author : Henrik Stegeby; Roland Lindh; Dage Sundholm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimatter; antiproton; matter-antimatter interactions; hydrogen-antihydrogen system; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Abstract : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.
