A Relativistic Equation-of-motion Coupled-Cluster Investigation of the Trends of Single and Double Ionization Potentials in the He and Be Isoelectronic Systems
Himadri Pathak, B. K. Sahoo, Turbasu Sengupta +3
We employ four-component spinor relativistic equation-of-motion coupled-cluster (EOMCC) method within the single- and double- excitation approximation to calculate the single ioniz…
Relativistic equation-of-motion coupled-cluster method for the double ionization potentials of the closed-shell atoms
Himadri Pathak, Aryya Ghosh, B. K. Sahoo +3
We report the general implementation of the relativistic equation-of-motion coupled-cluster method to calculate double ionization spectra (DI-EOMCC) of atomic and molecular systems…
Relativistic Spectroscopy of Plasma Embedded Li-like Systems with the Screening Effects in the Two-body Debye Potentials
Madhulita Das, B. K. Sahoo, Sourav Pal
The spectroscopic properties of Li atom and Li-like Ca and Ti ions in the plasma environment are investigated using a relativistic coupled-cluster (RCC) method. Assuming the plasma…
Relativistic Equation of Motion Coupled-Cluster Method: Application to the closed-shell atomic systems
Himadri Pathak, B. K. Sahoo, B. P. Das +2
We report our successful implementation of the full fledged relativistic equation of motion coupled cluster (EOMCC) method. This method is employed to compute the principal ionizat…
