By an octopole Jon-beam guide (OPIG) technique combined with a tandem massspectrometer technique, one- and two-electron capture cross sections of Ar" andKr" in their own gases have been measured in the wide collision energy range from 0. lto 1000 eV (in center-of-mass systems). By changing electron impact energy to pro-duce incident ions, contributions to cross sections from various ionic states in beamsare examined. Two-electrton capture cross sections are almost independent of ionicstates, but one-electron capture cross sections depend strongly on ionic states. One-electron capture cross sections by 'P state are determined at collision energies of 1.0,10 and 100 eV. In this paper, it is also shown that this OPIG experiment is very usefulfor low energy collision experiments and spans well the energy gap in previous ex-periments.
