Measurement of electric-dipole forbidden 3p and 3d level decay rates in Fe XII
Abstract
Based on measurements at the Heidelberg heavy-ion storage ring TSR, we present lifetimes of all six 3p and 3d levels of Fe XII that are long lived, due to the absence of E1 decay channels. We discuss the corresponding term analysis and the FeXII spectral lines that should be useful for the diagnostics of low density plasmas.
