Electron capture by slow Ne8+recoil ions

Electron capture from a metal surface by slow, multicharged aluminum and carbon ions.

A time-of-flight technique has been used to measure residual charge in the scattering of laserproduced pulses of ck + (k = 1 to 4) and. Alm + (m =2 to 5) ions from a well-outgassed amorphous gold-iridium surface under UHV conditions (2X Torr). Ions incident at 7' to the surface were specularly reflected. The analysis showed the survival of singly charged ions in the case of scattering 300-, 400...

Intrashell mixing following electron capture from atomic hydrogen targets by slow ions. I - Fully stripped projectiles

2014 The influence of the Stark effect on the l distribution of excited states produced by electron capture from atomic hydrogen into slow fully stripped ions is studied The Stark effect is strong enough, in these monoelectronic systems, to preclude any relation between the final l distribution and the primary process of electron capture. The latter determines the m distribution through « geome...

Electron capture by Ne 2 ¿ ions from atomic hydrogen

Using a merged-beam technique, the absolute, total electron-capture cross section has been measured for collisions of Ne ions with hydrogen ~deuterium! atoms at collision energies between 139 and 1490 eV/u. These data are compared to three other published measurements, two of which differ from one another by a factor greater than two. Early quantal rate coefficient calculations for Ne ions with...

Electron Emission from Surfaces Induced by Slow Ions and Atoms

Electron Capture by Highly Charged Ions from Surfaces and Gases

In this study highly charged ions produced in Electron Beam Ion Traps are used to investigate electron capture from surfaces and gases. The experiments with gas targets focus on spectroscopic measurements of the K-shell x-rays emitted at the end of radiative cascades following electron capture into Rydberg states of Ar and Ar ions as a function of collision energy. The ions are extracted from a...
