Investigation of some transitions and lifetimes in Xe ii

The lifetimes of the 6p ² D5/2ᵒ, 6p ⁴{P}5/2ᵒ$, 6p $⁴$ ${D}7/2ᵒ$, 6p $⁴D5/2ᵒ, and 6p ²{F}7/2ᵒ$ levels in Xe ii have been measured with a beam-laser technique. A detailed spectroscopic investigation of the fluorescence channels of the excited states has been performed to confirm the identifications. As a consequence of some reassignments experimental lifetime values can now unambiguously be ascribed to these levels.
