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 11OOA Sixty-five lines of Ne V have been newly identified. Fifty levels have been determined for the first time and energies have been revised for seven levels. [less ▲]

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 ions. As an example, we will describe the work undertaken at Liège on Ne IV and Ne V. Beam-foil is still the only general method for measuring the lifetime of atomic levels in highly charged ions. However, the accuracy of the classical beam-foil method is limited by the non-selective broadband excitation in the foil that populates almost all excitation levels up to very high energy and corrupts by cascading phenomena the normal single-exponential decay curves. We will describe some techniques that have been invented to obviate this infamous “cascading effect”, especially the beam-foil-laser spectroscopy method recently developed in our laboratory. We will present an overview of the beam-foil spectroscopy research performed at the University of Liège together with other recent trends in the field of fast-beam spectroscopy. [less ▲]

An accurate value for the radiative lifetime of the 2s2p2(4P)3s3P2 level in N II has been obtained using the beam-foil-laser spectroscopy method. The result (T = 0.456 ± 0.020 ns ) is shorter than the beam-foil lifetime values reported previously for the 3s' 3P term. No theoretical value for the lifetime of this term is available at the present time. [less ▲]
