Energy dependent relative charge transfer cross sections of Cs+ Rb(5s, 5p)
نویسندگان
چکیده
Magneto optical trap recoil ion momentum spectroscopy is used to measure energy-dependent charge exchange cross sections in the Cs + Rb(5s,5p) system over a range of projectile energies from 3.2 keV to 6.4 keV. The measurements are kinematically complete and yield cross sections that are differential in collision energy, scattering angle, and initial and final states.

Charge transfer cross sections at low energies and transfer ionization at high energies
We report a theoretical study of state-selective differential single-electron capture cross sections between Na and Rb(5s, 5p) atoms. The experimental data have been obtained with laser cooled target in a magnetic optical trap (MOT). We also report a theoretical study of transfer ionization of He by protons at high collision energies and analyze the transfer ionization cross section with respec...
متن کاملDifferential charge-transfer cross sections for Na with Rb collisions at low energies
We report on a theoretical and experimental study of state-selective differential single-electron transfer cross sections between Na ions and Rb(5s ,5p) atoms at collision energies of 2, 5, and 7 keV. A two-center multichannel semiclassical impact parameter close-coupling method with straight-line trajectories was used to obtain single-electron capture amplitudes. By combining with the eikonal ...
متن کاملLong-range potentials for two-species alkali-metal atoms
We address a growing interest in trapping and cooling of mixed-species alkali-metal atoms. Long-range coefficients that arise in the multipole expansion of molecular potentials for unlike alkali-metal dimers are calculated. The coefficients for the heteronuclear alkali-metal dimers corresponding to different molecular symmetries that separate to nS-n8S ,nS-n8P ,nS-n8D , and nP-n8P atomic levels...
متن کاملAnomalous depolarization of the 5 p 2 P 3 Õ 2 \ 8 p 2 Pj 8 transitions in atomic 87 Rb
Measurements of the linear polarization degree of the 5p P3/2→8p P j8 transitions ( j851/2,3/2) in atomic Rb are reported. The radiative transitions are electric-dipole forbidden, but electric-quadrupole allowed. In addition, because of the relatively strong spin-orbit interaction in Rb, the p-p transitions can acquire a magnetic-dipole transition strength that may be a measurable fraction of t...
متن کاملRubidium 5'P fine-structure transitions induced by collisions with potassium and caesium atoms
A diode-laser fluorescence experiment was performed in order to study fineStNCtUre transitions between 5'P states of rubidium atoms colliding with ground-state potassium or caesium atoms. The Rb(5'P,/,) state was optically excited and the intensity ratio of sensitized to direct fluorescence was measured. The obtained cross sections for the excitation energy transfer Rb('P,,J + Rb('PII2) induced...
