Observation of visible and uv magnetic dipole transitions in highly charged xenon and barium

We have observed an unusual transition which is predicted to result in visible and near-uv emission from very highly charged titaniumlike ions spanning the entire upper half of the periodic table. Measurements of the wavelengths of the 3[ital d][sup 4][ital D][sub 2]-[sup 5][ital D][sub 3] transitio...

Description
Summary:We have observed an unusual transition which is predicted to result in visible and near-uv emission from very highly charged titaniumlike ions spanning the entire upper half of the periodic table. Measurements of the wavelengths of the 3[ital d][sup 4][ital D][sub 2]-[sup 5][ital D][sub 3] transitions in Ba[sup +34] and Xe[sup +32] are in surprisingly poor agreement with [ital ab] [ital initio] calculations. This work was carried out in an electron beam ion trap and demonstrates that such a device can be an important tool for visible spectroscopy of highly charged ions.
