• Welcome to PPC-13
It is our pleasure to invite you to participate in the 13th International Workshop on Positron and Positronium Chemistry (PPC-13). The workshop will be held during 25 to 30 October 2020 in Kanazawa, Japan, actually 30th anniversary from the first PPC-3 held in 1990.
  • Scope

The scope of the meeting follows previous workshops, namely,
  1. Fundamental aspects of positron and Ps chemistry (interaction of positron and Ps with atoms, molecules or solid matter, Ps formation etc.)
  2. Positron chemistry for antimatter (antihydrogen, Ps, etc.) production
  3. Theoretical and computational chemistry for positron and Ps species
  4. Polymers and soft matter
  5. Liquids and multiphase systems
  6. Surfaces, interfaces, membranes and layered structures
  7. Porous materials, nanostructured and confined systems
  8. Materials for industrial applications (nuclear, hydrogen energy technology etc.)
  9. Other non-metallic solids
  10. Biological and medical applications of positron and Ps (e.g. Positron Emission Tomography)
  11. Advances in experimental techniques, including positron beams

  • Auspices

  • At the begining (From the preface of PPC-3)

The first PPC, that is, PPC-3 was convinced at ICPA-8 (Gent, Belgium, 1988) by several chemists and chemically oriented physicists, who met informally at dinner. Their feeling evolved in the conversation that three years between the triennial ICPA meetings is too long for the "rapidly" developing field at that time. Accordingly, it was decided to start a series of chemical meetings timed to come between the ICPA meetings.
It was realized that two previous meetings,
1. A positron workshop organized by H. J. Ache and D. M. Schrader in Blackburg, Virginia in 1979,
2. International Symposium on Positron Annihilation Studies of Fluids, organized by S. C. Sharma in Arlington, Texas in 1987,
could be interpreted as precursors, hence the "3" in PPC-3.
