Relativistic Atomic Structure Studies Via Density Functional Theory

摘要

Relativistic many-body treatment is essential for the study of structures and spectra of heavy atomic systems. In this talk we shall present our attempts to understand the atomic structure of heavy elements and super-heavy elements via a relativistic density functional theory. The relativity is taken care of by the kinematic description of Dirac electrons whereas the many-body aspect is incorporated through exchange-correlation processes. As practical applications the results of our calculations for the inner-shell structures of several heavy atoms will be presented. 18 refs. (Atomindex citation 18:015245)
