Measuring the branching ratios from the $y^8{\mathrm{P}}_{9/2}$ state to metastable states in europium

Abstract

We measure the branching ratios from the $y^8{\mathrm{P}}_{9/2}$ excited state to six metastable states of europium through fluorescence spectroscopy of an atomic beam. The sum of the six branching ratios is estimated to be $1.05(2)\times 10^{-3}$. This research provides us with insightful information to determine the feasibility of using the $a^8{\mathrm{S}}_{7/2}-y^8{\mathrm{P}}_{9/2}$ transition in order to implement the Zeeman slowing for europium atoms in the ground state. Based on this result, we also propose a scheme for Zeeman slowing and magneto-optical trapping, using a specific metastable state which has a cyclic transition.
