Spectroscopy of a narrow cooling transition in zinc — •Vedang Sumbre, Lukas Möller, David Röser, and Simon Stellmer — Physikalisches Institut, Universität Bonn, Nussallee 12, 53115 Bonn

Zinc has emerged as a strong candidate for a highly precise optical clock, due to its small sensitivity to black body radiation. We perform Doppler-free spectroscopy of the 307.6 nm 1S0 -> 3P1 transition on a thermal vapor of zinc atoms, and measure the isotope shifts of this transition for all the stable isotopes of Zinc.

Keywords: zinc; Doppler-free spectroscopy; isotope shifts
