Titanium 6-aluminum 4-vandium alloys were etched for varying periods of time in aqueous solution of hydrofluoric acid and ammonium dihydrogen phosphate. Following etching, one-half of the specimens were covered with vacuum evaporated gold while the o

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
