Abstract
The crossed-beam technique has been used to measure the absolute cross section for the process Ar++e to Ar2++2e at electron energies ranging from below threshold to 1000 eV. The cross section differs in shape from the trapped-ion data of Hasted and Awad (1972) but is in good absolute agreement with the semi-empirical calculation of Lotz (1968).Keywords
