Experimental INvestigation of radiative decay rates of metastable levels in Eu II

Research output: Contribution to journalArticle

Abstract

The radiative lifetimes of the metastable a 9DJ (J = 2-5) levels in Eu II have been measured by laser probing of a stored ion beam. The lifetimes of all four J levels are slightly above 1 s. A deviation from the expected energy dependence of the decay rates for electric quadrupole transitions is observed and discussed.
