The Authors have been devoted to production and compilation of experimental charge changing cross sections for ion-atom collisions since 1983, as a part of data center activities of JAERI.

We have measured single and double electron capture cross sections for Be⁺, Be²⁺ ions colliding with He, Ne, Ar, Kr, H₂, CO, CO₂, CH₄, C₂H₆, C₃H₈ atoms or molecules, B⁺, B²⁺ ions colliding with He, Ne, Ar, Kr, H₂, CO, CO₂ atoms or molecules, C⁺, C²⁺, C³⁺ ions colliding with H₂, CO₂, CH₄, C₂H₆, C₃H₈ molecules, Cr⁺, Cr²⁺ ions colliding with He, Ne, Ar, Kr, H₂, CO, CO₂, CH₄, C₂H₆, C₃H₈ atoms or molecules, Fe⁺ ion colliding with He, Ne, Ar, Kr, H₂, CO, CO₂, N₂, CH₄, C₂H₆, C₃H₈ atoms or molecules, and finally, Ni⁺, Ni²⁺ ions colliding with He, Ne, Ar, Kr, H₂, CO, CO₂, N₂, CH₄, C₂H₆, C₃H₈ atoms or molecules at 5-15 keV.

We have been compiling experimental total cross section data for electron capture or loss since 1983, and partial cross section data since 1992 published in journals of our selection. Experimental cross sections for some related interactions, like inner-shell ionization of target, ion-ion collisions, cluster collisions and so on, are also under the compilation since 1995.
All the compiled data after 1989 are stored numerically, including the case for only figures are published, and a new database interface is under the construction now.
