RCCPAC: A parallel relativistic coupled-cluster program for closed-shell and one-valence atoms and ions in FORTRAN
B. K. Mani, Siddhartha Chattopadhyay, D. Angom
We report the development of a parallel FORTRAN code, RCCPAC, to solve the relativistic coupled-cluster equations for closed-shell and one-valence atoms and ions. The parallelizati…
Plasma-screening effects in the atrophysically relevant He-like and Li-like Mg and Fe ions
B. K. Sahoo, Madhulita Das
The effect of plasma environment on the atomic energy levels of He-like and Li-like Mg and Fe ions have been studied using Debye model. The equation-of-motion coupled-cluster (EOMC…
Unexpectedly large difference of the electron density at the nucleus in the 4p P fine-structure doublet of Ca
C. Shi, F. Gebert, C. Gorges +9
We measured the isotope shift in the S-P (D2) transition in singly-ionized calcium ions using photon recoil spectroscopy. The high accuracy of the technique…
Determination of magic wavelengths for the transitions in Fr atom
Sukhjit Singh, B. K. Sahoo, Bindiya Arora
Magic wavelengthsfor the transitions in Fr were reported by Dammalapati \textit{et al.} in [Phys. Rev. A 93, 043407 (2016)]. These were det…
