Direct two-photon excitation of isomeric transition in thorium-229 nucleus
V. I. Romanenko, Ye. G. Udoviskaya, L. P. Yatsenko +3
A possibility of the two-photon excitation of an isomeric state in a nucleus of thorium-229 has been discussed. The fluorescence intensity of the excitation is demonstrated to be i…
Capture of atoms and small particles in an optical trap formed by sequences of counter-propagating light pulses with a large area
Victor I. Romanenko, Leonid P. Yatsenko
A new trap for atoms and small particles based on the interaction between an atom and the field of counter-propagating light pulses that are partially superposed in time has been p…
Performance of a 229 Thorium solid-state nuclear clock
G. A. Kazakov, A. N. Litvinov, V. I. Romanenko +5
The 7.8 eV nuclear isomer transition in 229 Thorium has been suggested as an etalon transition in a new type of optical frequency standard. Here we discuss the construction of a "s…
