Abstract
In a coincidence experiment, we have measured the absolute differential cross section for -shell ionization of Cu and Ag by 140-keV electrons. The results are discussed and compared with the calculations of Das and of Cooper and Kalbensvedt. While the agreement between experiment and theory is reasonable at 15°, there appears to be a sizable discrepancy at 45°, particularly at larger detected electron energy.
