Investigation of some transitions and lifetimes in Xe ii

Abstract
The lifetimes of the 6p 2 D5/2o, 6p 4 P5/2o, 6p 4 D7/2o, 6p 4 D5/2o, and 6p 2 F7/2o levels in Xe i i 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.
