Ab initio determination of polarizabilities and van der Waals coefficients of Li atoms using the relativistic CCSD(T) method
L. W. Wansbeek, B. K. Sahoo, R. G. E. Timmermans +2
We report a new technique to determine the van der Waals coeffcients of lithium (Li) atoms based on the relativistic coupled-cluster theory. These quantities are determined using t…
Intrinsic Electric Dipole Moments of Paramagnetic Atoms: Rubidium and Cesium
H. S. Nataraj, B. K. Sahoo, B. P. Das +1
The electric dipole moment (EDM) of paramagnetic atoms is sensitive to the intrinsic EDM contribution from that of its constituent electrons and a scalar--pseudo-scalar (S-PS) elec…
Electric quadrupole moment of the state in : A relativistic coupled-cluster analysis
K. V. P. Latha, C. Sur, R. K. chaudhuri +2
The electric quadrupole moment for the state of , has been calculated using the relativistic coupled-cluster method. Earlier a similar calcul…
Relativistic calculations of the lifetimes and hyperfine structure constants in Zn
Gopal Dixit, H. S. Nataraj, B. K. Sahoo +2
This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying…
Theoretical spectroscopic studies of the atomic transitions and lifetimes of low-lying states in Ti IV
Subhasish Mandal, Gopal Dixit, B. K. Sahoo +2
The astrophysically important electric quadrupole (E2) and magnetic dipole (M1) transitions for the low-lying states of triply ionized titanium (Ti IV) are calculated very accurate…
The electron electric dipole moment enhancement factors of Rubidium and Caesium atoms
H. S. Nataraj, B. K. Sahoo, B. P. Das +2
The enhancement factors of the electric dipole moment (EDM) of the ground states of two paramagnetic atoms; rubidium (Rb) and caesium (Cs) which are sensitive to the electron EDM a…
