New experimental and theoretical approach to the 3d D-level lifetimes of 40Ca+

A. Kreuter, C. Becher, G. P. T. Lancaster +8

We report measurements of the lifetimes of the 3d ${}^2$D${}_{5/2}$ and 3d ${}^2$D${}_{3/2}$ metastable states of a single laser-cooled ${}^{40}$Ca${}^{+}$ ion in a linear Paul trap. We introduc…
