“…Spectroscopic data for Be I also have significant importance in astrophysics. For example, properties related to transition probabilities are needed for diagnostics of astrophysical plasmas [1,2] . One of the methods for determining transition probabilities and oscillator strengths is through the combination of radiative lifetimes with branching fractions (BFs).…”

Radiative lifetimes of five levels in Be I lying in the energy range 64,506.45-71,160.52 cm −1 were measured by the time-resolved laser-induced fluorescence technique. These new data, together with previously measured radiative lifetimes and two reliable calculated lifetimes, were combined with branching fractions obtained from pseudo-relativistic Hartree-Fock calculations to deduce semi-empirical transition probabilities and oscillator strengths for 90 Be I spectral lines involving upper levels ranging from 42,565.35 to 72,251.27 cm −1 .

“…The systematics of level structures and spectra of highly ionized atoms has been reviewed by EdlCn [210,211] and Martinson [212,213]. Particular elements and particular isoelectronic sequences have been reviewed in a series of papers, most of them have been published in Physica Scripta, J, Opt.…”

Presently thermonuclear fusion research is faced with a number of atomic and molecular physics problems depending on the type of high-temperature plasma investigated. The present article discusses some particular atomic physics aspects in connection with magnetically confined plasmas (Tokamaks, Stellarators): (1) rate equations for density, momentum and energy with application to plasmas; (2) initial phase of Tokamak plasmas; (3) influence of impurity radiation on operating conditions of fusion plasmas in general and on Tokamak plasmas in particular; (4) influence of atomic elementary reactions on thermodynamic plasma properties; (5) level structures of highly ionized atoms; (6) spectroscopic diagnostic problems.
