HIGH RESOLUTION KRYPTON M_4.5 X-RAY EMISSION SPECTRA

Résumé
En utilisant le nouveau frôlant-incidence, reflexion-raseur M_4,5 (3d → 4p) monochromator/spectrometer, on a mesuré les spectres bien-resolus des rayons X du Plasma de krypton, avec les cours très grands du flux et aux ondes ultra-violets extremes et des rayons X doux. Le pouvoir nominal de la resolution de l'instrument, E/ΔE, est à peu près 300 dans ce regime d'énergie. On a observé, à 80.98, 80.35 et 79.73 eV, les trois (3d → 4p) lignes spectrales que le dipole permet. On a assigné, provisoirement, un pic large, à peu près 82.3 eV, aux transitions qui resultent du Kr²⁺. On a observé les effets sur des rayons X (M_4,5) de l'énergie d'excitation.

Abstract
High resolution M_4,5 (3d → 4p) x-ray emission spectra from a krypton plasma were measured using a recently developed grazing-incidence reflection-grating monochromator/spectrometer with very high flux rates at extreme ultraviolet and soft x-ray wavelengths. The nominal resolving power of the instrument, E/ΔE, is about 300 in this energy range (~80 eV). Three dipole-allowed 3d → 4p emission lines were observed at 80.98 eV, 80.35 eV and 79.73 eV. A broad peak at about 82.3 eV, is tentatively assigned to transitions resulting from Kr²⁺, and effects of excitation energy on M_4,5 x-ray emission were observed.
