Outline of Final Research Achievements

We try to measure absolute cross sections of charge exchange processes for tungsten multiply charged ions with hydrogen, deuterium and helium atoms, which data are useful for a simulation revealed transfer processes into main plasma of heavy elements. In addition, we have developed an apparatus to measure relative cross sections for hydrogen and deuterium atom targets. We have plan to observe an isotope effect on charge exchange processes using the apparatus.
