Correlation effects for nl-n′l′ transitions in nine isoelectronic sequences of silver ions

Abstract

We present a comprehensive theoretical study of atomic characteristics of nine isoelectronic sequences of silver ions in a broad range of wavelengths and transitions. Energy levels and transitions probabilities are calculated for nl–n′l′ transitions particularly in Ag XLV, Ag XLIV, Ag XLII, Ag XXXVII, Ag XXXVI, Ag XXXV, Ag XIX, Ag XVIII, Ag XVII ions. Atomic structure and radiative characteristics of Li-like, Be-like, B-like, Na-like, Mg-like, Al-like, Cu-like, Zn-like and Ga-like silver ions are computed by multiconfiguration Dirac–Fock (MCDF) and relativistic configuration interaction calculations (RCI). The valence–valence, core–valence and core–core correlations are also considered. The calculated values including core–valence correlation are found to be similar and to compare very well with other theoretical and experimental values. We believe that our extensive calculated values can guide experimentalists in identifying the fine-structure levels in their future work.
