Hanle lifetime measurements of SrI 1P1 and Cal 1P1 levels excited by a neutral beam of 1 1S0 helium atoms
Description
A 0.8 keV He(1 1S0) beam was used to coherently excite the 1P1 levels of Sr and Ca targets. The coherence appears as an alignment of the excited state with respect to the beam axis. We report here the results of a Hanle measurement, or a zero-field level-crossing experiment, performed on these coherently excited levels. The radiative lifetimes of the SrI 1P1 and Cal 1P1 levels were measured to be 4.7 ns and 5.3 ns, respectively. These values are in good agreement with conventional Hanle measurements. (orig.)
