A metastable state in $Yb^{+}$ with lifetime greater than 10 minutes

Hassan Farhat, William Liu, Wesley C. Campbell

We find through direct, time-domain measurement of trapped $Yb^{+}$ ions that the excited $^{3} [11/2]_{9/2}^{o}$ state has a collision-free lifetime of 17.8(6) min, long enoug…

Sub-hertz optical transitions in excited Yb $^{+}$

Patrick McMillin, Hassan Farhat, William Liu +1

We present the observation of three semi-forbidden transitions in singly-ionized ytterbium from the metastable $^{2} F_{7/2}^{o}$ state. Owing to the long lifetimes of both t…
