In this review, we discuss the current status of analytic derivative theory in relativistic
quantum chemistry. A brief overview of the basic theory for the available relativistic quantum …

We report the result of our ab initio calculation of the 6 s 2 S 1/2→ 5 d 2 D 3/2 parity
nonconserving electric dipole transition amplitude in Ba+ 137 based on relativistic coupled …

The relativistic coupled-cluster method is applied to calculate the magnetic dipole hyperfine
constant “A” of the 6 s 1/2, 6 p 1/2, 6 p 3/2, and 5 d 3/2 states of singly ionized barium. After …

Relativistic coupled-cluster theory has been employed to calculate the lifetime of the 6 2 P
3/2 state of singly ionized lead (207 Pb) and compared with the corresponding values …

We present our calculations of the electric dipole and quadrupole matrix elements for
transitions between low-lying bound states of Ba+ that are relevant for parity …

A practical high-accuracy relativistic method of atomic structure calculations for univalent
atoms is presented. The method is rooted in the coupled-cluster formalism and includes …

The perturbed relativistic coupled-cluster (PRCC) theory is applied to calculate the electric
dipole polarizabilities of alkaline-earth-metal atoms. The Dirac-Coulomb-Breit atomic …

We use perturbed relativistic coupled-cluster (PRCC) theory to calculate the electric dipole
polarizability of the noble-gas atoms Ar, Kr, Xe, and Rn. We also provide a detailed …

It is widely believed that the standard model of particle physics is just an intermediate step in
understanding the properties of the elementary physics in nature and the interactions …

The low-lying n (= 3, 4, 5) d D 5∕ 2 2 states of alkaline-earth-metal ions are of vital
importance in a number of different physical applications. The hyperfine structure constants …
