Abstract
The analysis of the spectrum of Yb rn has been extended allowing us to esta blish 11 new energy level values. In addition, radiative lifetimes of two e xcited states of Yb III have been measured for the first time using time-re solved laser-induced fluorescence following two-photon excitation. The good agreement between experimental results and semi-empirical calculations per formed with the relativistic Hartree-Fock method including core-polarizatio n effects allows the determination of transition probabilities for 15 lines .
