Lifetime measurements of highly excited levels of sr I using stepwise excitation by two pulsed dye lasers

  • Published:

Abstract

The lifetimes of higher lying1S0−,1D2−, and1F 03 -levels and of the 5s 7s3S1- and 5p2 3P1-state in the Sr I-spectrum have been measured by a time resolved registration of the fluorescent intensity. The1S0− and1D2-levels were populated selectively by a two step optical excitation using two pulsed dye lasers. In the case of the1F 03 -levels and of the3S1−,3P1-states the first excitation step was performed by a discharge, for the second, selective step a pulsed dye laser was used. The agreement of the experimental results with theoretically obtained lifetimes is satisfactory only in some cases.
