The intensities of the M5O3 and M5N3 characteristic x‐ray lines and the M5N4,5N4,5 Auger‐electron line from La were measured as functions of the electron excitation energy near the M5 ionization energy. The excitation curve of each of these emiss

When the excitation energy lies near the ionization potential of many core electrons, core-hole relaxation effects strongly affect x-ray emissions. Under near-threshold electron excitation of the cerium 4d subshell both the incident electron and a 4d

We have obtained soft x-ray appearance potential spectra of the N and M levels of samarium metal by scanning the electron excitation energy from 50 through 1560 eV. Newly observed line-like x-ray emission singularities are identified for excitation e

The interdiffusion of Al and Cr thin films from 659–726 K was investigated by measurements employing Auger electron spectroscopy (AES) and Ar ion beam sputtering. The only intermetallic phase observed at the Al–Cr interface of isothermally anneal
