Isotopic effect on collisional widths and shifts of Hg clock transition induced by cold Rb atoms

Renu Bala, Adam Linek, Marcin Witkowski +7

We study the isotopic dependence of collisional widths and shifts of the Hg clock transition ${}^1$S${}_0$-${}^3$P${}_0$ perturbed by the Rb atoms in the temperature range from 1 nK to 1 K…
