Perturbed Coupled-Cluster theory to calculate dipole polarizabilities of closed shell systems: Application to Ar, Kr, Xe and Rn
S. Chattopadhyay, B. K. Mani, D. Angom
We use perturbed relativistic coupled-cluster (PRCC) theory to calculate the electric dipole polarizability of noble gas atoms Ar, Kr, Xe and Rn. We also provide a detailed descrip…
Ba Quadrupole Polarizabilities: Theory versus Experiment
B. K. Sahoo, B. P. Das
Three different measurements have been reported for the ground state quadrupole polarizability in the singly ionized barium (Ba) which disagree with each other. Our calculation…
Revisiting Nuclear Quadrupole Moments in K Isotopes
Yashpal Singh, D. K. Nandy, B. K. Sahoo
Nuclear quadrupole moments (s) in three isotopes of potassium (K) with atomic mass numbers 39, 40 and 41 are evaluated more precisely in this work. The value of K is…
Electric dipole polarizability from perturbed Relativistic Coupled-Cluster Theory: application to Neon
S. Chattopadhyay, B. K. Mani, D. Angom
We develop a method based on the relativistic coupled-cluster theory to incorporate a perturbative interaction to the no-pair Dirac-Coulomb atomic Hamiltonian. The method is genera…
Fock space relativistic coupled-Cluster calculations of Two-Valence Atoms
B. K. Mani, D. Angom
We have developed an all particle Fock-space relativistic coupled-cluster method for two-valence atomic systems. We then describe a scheme to employ the coupled-cluster wave functi…
A Reappraisal of the Electric Dipole Moment Enhancement Factor for Thallium
H. S. Nataraj, B. K. Sahoo, B. P. Das +1
The electric dipole moment (EDM) enhancement factor of atomic Tl is of considerable interest as it has been used in determining the most accurate intrinsic electron EDM limit to da…
