Lifetimes and transition probabilities in Kr V

Weighted oscillator strengths (gf), weighted transition probabilities (gA) and lifetimes are presented for all experimentally known dipole transitions and levels of Kr V. Values were determined by four methods. Three of them are based on the Hartree–Fock method, including relativistic corrections and core-polarization effects, with electrostatic parameters optimized by a least-squares procedure in order to obtain energy levels adjusted to the corresponding experimental values. The fourth method is based on a relativistic multiconfigurational Dirac–Fock approach. In addition, 47 new classified lines belonging to the Kr V spectrum are presented. ► Atomic transitions for Kr V were determined. ► The experimental data were obtained from a capillary-discharge tube and a optimized theta pinch. ► Multiconfiguration Hartree–Fock calculations with relativistic corrections including core-polarization effects were used. ► Weighted oscillator strengths (gf), transition probabilities and lifetimes were determined. ► Multiconfigurational Dirac–Fock approach were also used.
