Fusion-Related Ionization and Recombination Data for Tungsten Ions in Low to Moderately High Charge States

Fusion-Related Ionization and Recombination Data for Tungsten Ions in Low to Moderately High Charge States

Collisional processes and details of atomic structure of heavy many-electron atoms and ions are not yet understood in a fully satisfying manner. Experimental studies are required for guiding new theoretical approaches. In response to fusion-related needs for collisional and spectroscopic data on tun...
