Abstract: We continue the work exposed in Lecavelier des Étangs et al. (2000) concerning a possible detection of fluorescence emission from Fe II ions inside the β Pictoris gaseous disk. We use new data (2001) obtained with HSTSTIS but cannot confirm the previous results. We calculate the maximum Fe II column density at 10 AU from the center star, in the South-West extension of the disk: N(Fe II)10 AU ~ 1012 cm−2.
