Measured Lifetimes of Selected Metastable Levels of Arq+ Ions (Q=2, 3, 9, and 10) Stored in an Electrostatic Ion-Trap
(American Physical Society, 1994)
Metastable multiply charged argon ions produced in, and extracted from, an electron cyclotron resonance ion source were captured from the beam into an electrostatic (Kingdon) ion trap by rapidly pulsing the potential of ...
Excited-Level Lifetimes and Hyperfine-Structure Measurements on Ions using Collinear Laser Ion-Beam Spectroscopy
(American Physical Society, 1994)
The mean lifetimes tau of the Ca II 4p P-2(1/2) and 4p P-2(3/2) levels, and the Cl-35 II 4p' F-1(3) level, have been measured by a variant of the collinear laser-ion-beam lifetime technique applied previously to the Ar II ...
Collinear Laser-Beam Ion-Beam Measurement of the Mean Lifetime of the Ar Ii 4p'2f-Degrees-7/2 Level
(American Physical Society, 1993)
The mean lifetime tau of the 4p'F-2(7/2)-degrees level of Ar II has been measured using a variant of the collinear laser-beam-fast-ion-beam spectroscopy technique. Our variant requires no mechanical motion or laser frequency ...
