Relativistic study of the nuclear anapole moment effects in diatomic molecules
Nuclear-spin-dependent (NSD) parity violating effects are studied for a
number of diatomic molecules using relativistic Hartree-Fock and density
functional theory and accounting for core polarization effects. Heavy diatomic
molecules are good candidates for the successful measurement of the nuclear
anapole moment, which is the dominant NSD parity violation term in heavy
elements. Improved results for the molecules studied in our previous
publication [Borschevsky et al., Phys. Rev. A 85, 052509 (2012)] are presented
along with the calculations for a number of new promising candidates for the
nuclear anapole measurements.Comment: 7 pages, 1 figure. arXiv admin note: substantial text overlap with

Sequential decoupling of negative-energy states in Douglas-Kroll-Hess theory
Here, we review the historical development, current status, and prospects of
Douglas--Kroll--Hess theory as a quantum chemical relativistic electrons-only
theory.Comment: 15 page
