Experimental and theoretical study of the Kr L-shell Auger decay

The LMM Auger spectra of krypton are measured using the photon energies hv = 1709 eV, 1792 eV, 1950 eV, and 13 keV. This approach allows separating the contributions from the various core holes L-1 , L-2., and L-3. Previously unobserved transitions are presented. Complementary theoretical work is performed allowing the assignment of the spectral features. The L2,3Y -MMY (Y = M-4,M-5, N-1,N-2,N-3) Auger transitions of Kr2+ formed via Coster-Kronig Auger decay of the core holes L-1 and L-2. are also investigated. These spectra comprise about 4000 and 13 000 transitions, respectively, so that only general statements on the assignment, such as the configurations involved in the transitions, can be given.

Automated summary

The LMM Auger spectra of krypton were measured at different photon energies, presenting previously unobserved transitions and allowing for the assignment of spectral features through complementary theoretical work. Additionally, the L2,3Y-MMY Auger transitions of Kr2+ formed via Coster-Kronig Auger decay of core holes L-1 and L-2 were investigated, with about 4000 and 13,000 transitions respectively, leading to general statements on the assignment of configurations involved in the transitions.
