RIKEN Atomic Physics Laboratory

The Laboratory aims at a comprehensive understanding of (i) dynamic interactions of exotic charged particles such as multiply charged ions, radioactive ions, antiprotons, etc. of meV to GeV range with various targets and (ii) atomic properties of collision products keeping widespread view over neighboring fields like surface physics, radiation physics, nuclear physics, and physical chemistry.
