Abstract

Experimental cross sections are reported for electron excitation of the allowed [Formula Presented] transition in [Formula Presented] Center-of-mass energies are from below threshold (7.00 eV), through threshold (8.00 eV), and up to approximately 1.5 times the threshold (12 eV). The present results are found to overlap earlier energy-loss data reported to energies of 8.45 eV. The data are also compared with other optical-emission results for this dipole-allowed transition and with several theoretical calculations. An “electronic aperture” is described that allows discrimination against elastically scattered electrons, with their larger Larmor radii, in experiments with magnetically confined ions or electrons.
