Scientific paper

IUE spectra of the Beryllium II region are presented for two Lithium-rich giant stars, HD 9746 and HD 112127. In either spectrum there is no sign of significant Beryllium features at the BeII lines 3130.416Å or 3131.064Å, which seems to indicate that Be was depleted in these two Lithium-rich giants. This suggests that some additional Lithium was produced in their stellar interiors during the evolution along the giant branch.
