Abstract (from CDS):

In a previous work we studied the IRAS colours of known Li-rich red giants and showed that they have flux ratios F12/F25 and F25/F60 in well defined ranges. By using this result as a selection criterion, we prepared a list of 280 IRAS Point Source candidates to be Li-rich giant stars. Up to the present we have obtained spectra for 57% of our target list. We identified five stars showing a strong LiI 670.079nm line and six ones with a Li line of medium strength. Most of the candidates show features typical of normal giants having circumstellar dust, as indicated by their IRAS colours.
