The cross sections for ionization and excitation into Rydberg states (n = 21-27) were determined for fast (accelerated to 3.9 keV) metastable helium atoms colliding with He, Ne, and N, .An analysis of the collisionally excited helium atoms in terms of their principal quantum number was carried out using for the ionization by an electric field a system capable of separation in accordance with n and was calibrated using signals from Rydberg states excited selectively by laser radiation.

Collisional quenching and j -mixing rate constants for the 3D levels of Ca+

Martina Knoop, M. Vedel, F. Vedel

Collisional relaxation and fine-structure mixing rate constants have been measured for the metastable $D$ doublet ${(3D}_{3/2},$ ${3D}_{5/2})$ of ${\mathrm{Ca}}^{+}$ ions in the presence of different neutral gases completing a previous work. Experimental results are given for He, Ne, Ar, ${\mathrm{H}}_{2},$ ${\mathrm{N}}_{2},$ and ${\mathrm{CH}}_{4}.$ These data have been obtained with a cloud of approximately ${10}^{5}$ ${\mathrm{Ca}}^{+}$ ions stored in a Paul trap at kinetic energies of around 1 eV. The investigated levels were populated by direct excitation of the corresponding $4S\ensuremath{-}3D$ transitions. The involved time constants were determined from the temporal evolution of the fluorescence of one of the resonance transitions, following the optical pumping of the $P$ level from the $D$ component. Comparison of our data with other similar experimental and theoretical work is finally presented.Collisional relaxation and fine-structure mixing rate constants have been measured for the metastable $D$ doublet ${(3D}_{3/2},$ ${3D}_{5/2})$ of ${\mathrm{Ca}}^{+}$ ions in the presence of different neutral gases completing a previous work.
