Electric dipole polarizabilities of alkali metal ions from perturbed relativistic coupled-cluster theory
S. Chattopadhyay, B. K. Mani, D. Angom
We use the perturbed relativistic coupled-cluster theory to compute the static electric dipole polarizabilities of the singly ionized alkali atoms, namely, Na, , Rb, Cs…
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…
Transition properties of potassium atom
D. K. Nandy, Yashpal Singh, B. P. Shah +1
We report here oscillator strengths, transition rates, branching ratios and lifetimes due to allowed transitions in potassium (K) atom. We evaluate electric dipole (E1) amplitudes…
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…
State-insensitive trapping of Rb atoms: linearly versus circularly polarized lights
Bindiya Arora, B. K. Sahoo
We study the cancellation of differential ac Stark shifts in the 5s and 5p states of rubidium atom using the linearly and circularly polarized lights by calculating their dynamic p…
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…
