Effects of autoionization in electron loss from helium-like highly charged ions in collisions with photons and fast atomic particles
K. N. Lyashchenko, O. Yu. Andreev, A. B. Voitkiv
We study theoretically single electron loss from helium-like highly charged ions involving excitation and decay of autoionizing states of the ion. Electron loss is caused by either…
Ultra-stable optical clock with two cold-atom ensembles
M. Schioppo, R. C. Brown, W. F. McGrew +10
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation…
Spin dynamics in Kapitza-Dirac scattering of electrons from bichromatic laser fields
Matthias M. Dellweg, Hani M. Awwad, Carsten Müller
Kapitza-Dirac scattering of nonrelativistic electrons from counterpropagating bichromatic laser waves of linear polarization is studied. The focus lies on the electronic spin dynam…
Development of a strontium optical lattice clock for the SOC mission on the ISS
S. Origlia, S. Schiller, M. S. Pramod +25
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests…
