Outline of Final Research Achievements |
Although laboratory studies on physics of matter-antimatter plasmas which are supposed important to explore the dynamical development of the universe were regarded unlikely because of their short life time, a break-through was made by a success of producing stable ion-pair plasmas in laboratories and experimental studies have been started. Among them dispersion relations observed in an ion-pair plasma had been kept unexplained over 10 years in spite of many efforts of theoreticians of plasma physics. Noticing that the theoretical frame work used so far was not appropriate for the plasma in which the ion Lamor radius was compatible with the plasma radius, we have formulated a kinetic theory by taking account of exact ion trajectories in phase space and obtained the theoretical dispersion relations which showed excellent agreement with the observed dispersion relations. Furthermore a fluid theory with the gyro-viscosity is shown to recreate the same dispersion relations of basic modes.
