Charge state fractions of lead ions formed in one-electron capture collisions by fast H~+ and He~(2+) ions

摘要

A crossed beam coincidence counting technique incorporating time of flight analysis of target charged products has been used to measure the charge state fractions of slow multiply charged Pb~(q+) ions formed in one-elelctron capture by H~+ and He~(2+) ions in single collisions with ground state Pb atoms within the energy range 50-600keV amu~(-1). an attempt has been made to describe the measured fractions of Pb~(q+) ions for q chemical bounds 1-8 in terms of a simple model based on an independent electron description.
