Theoretical transition probabilities have been obtained for 54 n = 3 transitions depopulating the 3s3p 1Po, 3p2 3P, 1D, 1S, 3s3d 1D, 3D and 3p3d 3Po, 3Do, 3Fo, 1Fo, 1Do, 1Po levels, including 14 transitions not yet observed. Some of these predictions

Peculiar properties of ion-atom collision systems, in particular deviations from statistical populations of singlet and triplet levels, can be studied by optical spectroscopy. We have extended earlier studies by VUV spectroscopy of a number of collis

The equilibrium charge-state distributions have been measured for sodium ions at the exit of a carbon foil for energies ranging from 0.43 to 1.66 MeV. A comparison of our results with available models is performed and an empirical formula for calcula

Previous works devoted to the Ne V spectrum are very fragmentary and yield a rather controversial picture of this ion. A lot of unidentified lines are still reported in these multiple studies. In the present paper, Hartree-Fock calculations and least

Spectra and decay curves of boron-like (Na VII) and beryllium-like (Na VIII) sodium ions produced by beam-foil excitation have been recorded in the 30-60 nm spectral range and the radiative lifetimes of seven n=2 levels have been measured. The experi

A new investigation of the Ne V spectrum is reported. The beam-foil method has been used to produce spectra at two different energies (1.2 MeV and 2.5 MeV) between 450 and 1100 A. Sixty-five lines of Ne V have been newly identified. Fifty levels have

The beam-foil source can produce spectra of almost every ion and allows easy measurement of atomic lifetimes of excited levels. Beam-foil spectra have some unique characteristics that made them valuable tool for the term analysis of highly charged io

An accurate value for the radiative lifetime of the 2s 2p 2 ( 4 P) 3s 3 P 2 level in N II has been obtained using the beam-foil-laser spectroscopy method. The result (τ=0.456±0.020 ns) is shorter than the beam-foil lifetime values reported previous

We have obtained accurate values for the radiative lifetimes of the 2p 3d1D0 and 2p 3d3P2o levels in NII by the cascade-free beam-foil-laser spectroscopy method. Our results are τ(2p 3d1D0)=0.346±0.012 ns and τ(2p 3d3P2o)=0.457±0.020 ns. Comparis

Accurate lifetimes measured by means of the cascade-free method based on laser excitation of a fast ion beam preexcited in a carbon foil are reported for four 2p 3d levels in NII. The lifetime results are: τ(2p 3d3D 1 0 )=0.209±0.007 ns, τ(2p 3d3D
