| Outline of Final Research Achievements |
A negatively charged particle (X-particle) having a much heavier mass than a proton has been predicted by supersymmetry theory. Exotic atom and molecule can be formed, when one of electrons in an atom is replaced by the X-particle. The system is expected to exhibit unique properties which can not be found in typical atoms and molecules. X particles is considered to have generated just after the Big Bang, and nuclear reactions via X particle atomic collisions. In particular, it is expected to solve the lithium problem where calculated abundances of lithium isotopes are in disagreement with observed value. In this study, we performed precise calculations on exact quantum mechanical scattering problem for the X particle atomic collision, and discussed the properties of the X-particle.
