Calculations with spectroscopic accuracy: Energies, transition rates,and Lande gJ-factors in the carbon isoelectronic sequence from Ar XIII to Zn XXV

Extensive self-consistent multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and subsequent relativistic configuration interaction calculations are performed for 262 states belonging to the 15 configurations 2s 2 2p 2 ,2 s2p 3 ,2 p 4 ,2 s 2 2p3l, 2s2p 2 3l ,2 p 3 3l and 2s 2 2p4l (l = 0, 1, 2) in selected carbon-like ions from Ar XIII to Zn XXV. Electron correlation effects are accounted for through large configuration state function expansions. Calculated energy levels are compared with existing theoretical calculations and data from the Chianti and NIST databases. In addition, Lande gJ-factors and radiative electric dipole transition rates are given for all ions. The accuracy of the calculations are high enough to facilitate the identification of observed spectral lines.

Application of Ultra-fast Timing Techniques to the Study of Exotic and Weakly Produced Nuclei

Ultra-fast time-delayed techniques have been recently applied in a number of studies where exotic nuclei were identified using advanced selection techniques. These include large Compton-suppressed ...
