We experimentally study atomic, molecular and optical (AMO) physics using a new approach and viewpoint, covering a wide range of field; low-energy chemical evolution of molecules in space and dynamics of large molecules from high to low temperature environment, interaction of high-energy atoms with crystals, and spectroscopy of exotic atoms including negative muon and positron. From these purposes, we develop and utilize ion storage ring and trap, high energy highly charged ion beam or muon beam supplied from accelerators, combined with a variety of laser systems.
