【 摘 要 】

We measure the branching ratios from the y(8)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) x 10(-3). This research provides us with insightful information to determine the feasibility of using the alpha S-8(7/2) - y(8)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.
