摘要：

Proton excitation is suggested for the X-ray spectrochemical analysis of light elements; a 200-kV proton source and a flat crystal X-ray spectrometer are used. Measurements of the X-ray spectra of B-Kα and C-Kα show that proton excitation is promising for analyses in the soft X-ray region. For boron in nickel base alloy and carbon in low alloy steel and white iron, the calibration curves obtained showed excellent linearity. The detection limits were 0.0014% for boron and 0.0090%, for carbon for counting times of 1 min. © 1969.
