Electron-capture, electron-loss, and impact-ionization cross sections for 103- to 3400-keV/amu multicharged iron ions colliding with molecular hydrogen

Journal Article · · Phys. Rev. A; (United States)
We report cross-section measurements for collisions of multicharged iron ions with a molecular-hydrogen target: (a) electron capture and electron loss of the multicharged ions, and (b) impact ionization of the hydrogen target. Iron ions, Fe/sup +q/, were used with charge states q = 3--13 at 103 keV/amu, q = 9--16 at 294 keV/amu, q = 11--22 at 1160 keV/amu, and q = 20--25 at 3400 keV/amu. We find that an empirically determined expression for the electron-capture cross section, sigma = (1.2 x 10/sup -8/) q/sup 3.15/E(keV/amu)/sup -4.48/ cm/sup 2//molecule, describes all the data at and above 275 keV/amu. These measurements are compared with recent theoretical calculations.
