Abstract
The optical-excitation-function method has been used in a crossed-atom and electron-beam arrangement to measure the electron-impact cross section of the copper 4 $^{2}$P\ensuremath{\rightarrow}4 $^{2}$S resonance lines (324.8, 327.4 nm) from threshold (3.8 eV) to 8 eV. Relative experimental cross-section data are normalized at an energy of 1000 eV with respect to first Born theory that includes the 4 $^{2}$S\ensuremath{\rightarrow}4 $^{2}$P resonance transition with an oscillator strength of 0.652 and cascading from the (3${\mathit{d}}^{10}$nd${)}^{2}$D states with n=4,...,10. The measured Cu 4 $^{2}$S\ensuremath{\rightarrow}4 $^{2}$P cross section is compared with recent theoretical calculations in close-coupling approximation. Very good agreement is found with the ten-state close-coupling theory of Scheibner and Hazi (private communication).
