Recent advancements in atomic many-body methods for high-precision studies of isotope shifts
B. K. Sahoo, S. Blundell, A. V. Oleynichenko +3
The development of atomic many-body methods, capable of incorporating electron correlation effects accurately, is required for isotope shift (IS) studies. In combination with preci…
Radiative lifetime of the A 2Î 1/2 state in RaF with relevance to laser cooling
M. Athanasakis-Kaklamanakis, S. G. Wilkins, P. Lassègues +38
The radiative lifetime of the (v=0) state in radium monofluoride (RaF) is measured to be 35(1) ns. The lifetime of this state and the related decay rate $Î= 2.86…
Excitation of the Th nucleus by the hole in the inner electronic shells
M. G. Kozlov, A. V. Oleynichenko, D. Budker +6
The Th nucleus has a long-lived isomeric state at 8.338(24) eV [Kraemer et al, Nature, \textbf{617}, 706 (2023)]. This state is connected to the ground state by an M1…
Optical cycling in charged complexes with Ra-N bonds
Timur Isaev, Alexander V. Oleynichenko, Dmitrii A. Makinskii +1
The extension of laser cooling and trapping techniques to polyatomic molecular ions would have advanced scientific applications such as search of physics outside of the Standard Mo…
