Combining experiments and relativistic theory for establishing accurate radiative quantities in atoms: the lifetime of the $^{2}$ P $_{3/2}$ state in $^{40}$ Ca $^{+}$

Ziv Meir, Mudit Sinhal, Marianna S. Safronova +1

We report a precise determination of the lifetime of the (4p) $^{2}$ P $_{3/2}$ state of $^{40}$ Ca $^{+}$ , $τ_{P_{3/2}} = 6.639 (42)$ ns, using a combination of measurements of the i…

Cold molecular ions on a chip

A. Mokhberi, S. Willitsch

We report the sympathetic cooling and Coulomb crystallization of molecular ions above the surface of an ion-trap chip. N $_{2}^{+}$ and CaH $^{+}$ ions were confined in a surface-electrode…
