The atomic and molecular data on physical processes in fusion research are described. These data will be confirmed by experiment and theory in the future.
In particular, it is emphasized that the physical mechanics method, the theoretical basic of which is the atomic and moleculartheory, is important to the radiation characteristic research for plume.
