In the present work, we report on the analysis of archaeological metal artefacts from Late Bronze Age, performed by means of Laser Induced Breakdown Spectroscopy (LIBS). The experiment was carried out at ambient air and at 1064 nm of a Nd:YAG laser w

We report a new set oftheoretical transition probabilities in Y II, obtained using a multicon- figuration relativistic Hartree-Fock method including core polarization. The overall quality of the calculations is assessed by comparisons with new and pr

Radiative lifetimes of 17 excited levels of Nb I, in the energy range 27 400–47 700 cm −1 5s6p o 4 F ◦ 3/2,5/2,7/2,9/2), have been measured. For 15 of these levels, the lifetimes are obtained for the first time. The lifetimes were measured usin
