NICKEL L-ALPHA SPECTRA MEASURED BY A HIGH-RESOLUTION PARTICLE INDUCED X-RAY-EMISSION (PIXE) SPECTROMETER

The satellite spectra of Ni Lalpha X-rays induced by 21.0 MeV/amu N2+ ion bombardment were measured using a high-resolution soft X-ray spectrometer which was specially designed for the chemical state analysis by PIXE. We succeeded in observing two distinguished satellite lines, whose energies were estimated by the use of a relativistic self-consistent field program. Relative intensities of the satellites observed here were also well reproduced by theoretical values estimated from the semiclassical approximation after correcting the X-ray selfabsorption. The satellites were confirmed to originate from the multiply ionized states with one L3 and n M electron vacancies.
