摘要：

Differential cross sections have been measured for the electron-impact excitation of a multiply charged ion. In a crossed-beam experiment the resonant 3s-3p transition of sodiumlike Ar7+ is studied at an electron energy of 100 eV in an angular range between 13-degrees and 29-degrees. The experimental cross sections are found to be in good agreement with theoretical predictions obtained in Coulomb-Born distorted-wave approximation.
