Measurement of K–L radiative vacancy transfer probabilities in selected rare earth elements bombarded with 3–4MeV protons

Abstract: K-shell X-ray intensity ratios for selected rare earth elements were measured following irradiation with proton beams having energies between 3 and 4MeV. Using the X-ray intensity ratios, the radiative vacancy transfer probabilities from the shell K to the L sub-shells were determined. The experimental data were compared to theoretical predictions for X-ray line intensities and radiative vacancy transfer probabilities. The results showed a good agreement between theory and experiment. [Copyright &y& Elsevier]
