Magnetic dipole transition rates from measured lifetimes of levels of Be-like and B-like argon ions
(American Physical Society, 1998)
The lifetimes of the 1s(2)2s2p P-3(2) level of Ar XV and 1s(2)2s(2)2p P-2(3/2) of Ar XIV have been measured using metastable Ar14+ and Ar13+ ions produced by an electron cyclotron resonance ion source, which were subsequently ...
Electron-Transfer Collisions of Low-Energy Multicharged Nitrogen-Ions with H-2 and N-2
(American Physical Society, 1987)
Alignment of He-Like and H-Like P-States of 48-Mev Foil Excited mg Ions

Inversionless lasing with self-generated driving field
(American Physical Society, 2001)
We propose and study resonant ladder schemes of inversionless lasing on a fast-decaying transition when the population inversion is not possible or Very difficult to achieve. The driving field on a neighboring, slowly ...
Charge-Transfer from Molecular-Hydrogen to Stored O-2+ and O-3+ Ions
(American Physical Society, 1989)
Direct Observation of Hyperfine Quenching of the (2)3p0 Level in Helium-Like Nickel
(American Physical Society, 1991)
We report a clear demonstration of the effect of hyperfine quenching of a forbidden transition by direct comparison of the lifetimes of the 2 3P0 level in the heliumlike isotopes Ni-61(26+) and Ni-58(26+). We find the ...
Electron-Transfer from H-2 and Ar to Stored Multiply Charged Argon Ions Produced by Synchrotron Radiation
(American Physical Society, 1992)
The rate coefficients for electron transfer from Ar and H-2 to Ar(q+) ions (3 less-than-or-equal-to q less-than-or-equal-to 6) have been measured using an ion-storage technique in a Penning ion trap. The ions were produced ...
Measurement of a magnetic-dipole transition probability in Xe32+ using an electron-beam ion trap
(American Physical Society, 1997)
The transition probability for the 3d(4) D-5(2) <-- D-5(3) magnetic-dipole transition in Ti-like Xe (Xe32+) has been measured using an electron-beam ion trap. The unusually weak dependence of the transition energy on nuclear ...
Quenching Collisions of Low-Energy Metastable Multiply-Charged Argon Ions
(American Physical Society, 1994)
Quenching rates have been measured for selected metastable levels of Ar(q+) ions (q = 2, 3, 9, and 10) stored in a Kingdon ion trap, with mean energies of 262q eV and 181q eV. Effective quenching cross sections derived ...
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 ...
