Theory and Background #

Rubidium is known to exhibit some Coster-Kronig transitions, however these all exist in the L-shell and should not impact analysis unless specifically looking at higher energy orbitals using HAXPES.

Experimental Advice #

Rubidium deposited onto material surfaces to study alkali behaviour may potentially desorb under radiative stimuli (i.e. light), which is dependant on energy. Care should be taken to avoid excessive exposure to such sources.(3)

Rubidium is highly reactive, and can form compounds with chamber gases, even under ultra-high vacuum.

Data Analysis Guidance #

Rubidium has a relatively small doublet separation, so fitting multiple state of overlapping species requires high quality spectra.
