The collaboration between the University of Bonn and Imperial College on the use of synchrotron radiation for the observation of atomic absorption spectra has yielded much new data since IAU Colloquium No.27 (see also E. Radtke's paper in the present meeting). Among recently observed spectra are those of Tl I, In I, Ga I, Pb I, Sn I and Ge I, while earlier data on Zn I and Cd I have been extended to include double excitations. The first evidence of strong mixing between the d-np channel and double excitations at the same energy has come for Tl I where some of the expected d-np series are absent and, instead, other additional series appear.
