Detection in the interstellar medium of the weak [Mg II] transition at 1398.8 Å.
DESTREE J.D., WILLIAMSON K.E. and SNOW T.P.
Abstract (from CDS):
High- and medium-resolution ultraviolet spectra from the Space Telescope Imaging Spectrograph and the Goddard High Resolution Spectrograph were used to search for the weak electric quadrupole transitions of [Mg II] near 1398.8 Å. This forbidden doublet was detected in eight sight lines. We calculate an empirical f-value of (1.29±0.13)x10–5 from all detections and discuss prospects of using this weak line in future studies of translucent interstellar clouds and in damped Lyα systems.
