Radiative lifetime and oscillator strength determinations in Sm III

Atomic structure, radiative lifetime and oscillator strength calculations in doubly ionized molybdenum (Mo III)

Radiative lifetimes, transition probabilities and oscillator strengths in doubly ionized molybdenum (Mo III) are reported for the first time in the present paper. This new set of atomic data has been obtained by using a semi-empirical computational technique based on the pseudorelativistic Hartree–Fock approach in which a large amount of intravalence and core–valence electron correlations were ...

SELECTED LIFETIME AND OSCILLATOR STRENGTH MEASUREMENTS IN Si II

We have remeasured the lifetimes of the 3s24s and levels in Si II using beam foil spectro3s25s 2S1@2 scopic techniques. Measured values for the lifetimes and oscillator strengths derived from them are presented and compared with previous measurements and theoretical calculations. Agreement with recent theoretical calculations is now quite good : for 3s24s it is excellent and for 3s25s it is sat...

Tradeoffs between oscillator strength and lifetime in terahertz quantum cascade lasers

Radiative lifetime of excitons in carbon nanotubes.

We calculate the radiative lifetime and energy bandstructure of excitons in semiconducting carbon nanotubes within a tight-binding approach including the electron-hole correlations via the Bethe-Salpeter equation. In the limit of rapid interband thermalization, the radiative decay rate is maximized at intermediate temperatures and decreases at low temperature because the lowest-energy excitons ...
