چکیده

We predict ionization potentials of superheavy elements No, Lr, and Rf and their ions using a relativistic hybrid method that combines configuration interaction (CI) with the linearized coupled-cluster approach. Extensive study of the completeness of the four-electron CI calculations for Hf and Rf was carried out. As a test of theoretical accuracy, we also calculated ionization potential of Yb, Lu, Hf, and their ions, which are homologues of the superheavy elements of this study.

Detection technique with single-ion sensitivity for high-precision mass measurements on superheavy elements

Mass values contribute to a number of physical models: these range from masses of exotic short-lived nuclides being important for weak interaction studies and the Standard Model of particle physics, to stable masses as means for the definition of fundamental constants [1]. Since the discovery of the superheavy elements from to , the investigations in their masses have become more and more impor...

Abstract Background: Rheumatoid Arthritis, (RA) is a chronic inflammatory autoimmune disease with a progressive course requiring early diagnosis and treatment. The value of anti-cyclic citrullinated peptide antibodies (Anti-CCP) in the diagnosis of RA has been shown in several studies. The present study was designed to determine and compare the diagnostic value of Anti-CCP and rheumatoid fac...

Optical Spectroscopy of Trans-Fermium Elements at SHIPTRAP

An ultra sensitive laser spectroscopic method is being developed for the investigation of the completely unknown atomic structure of the elements No and Lr. Such experiments aim in the investigation of relativistic effects. These, roughly speaking, originate from a shrinkage of the wave functions of inner shell electrons which, in turn, influence the binding energy of the valence electrons and ...

Fully Relativistic ab initio Calculations of the Electronic Structures of the Superheavy Atoms

In order to obtain accurate results from quantum chemical calculations on systems containing heavy atoms, relativistic effects must be accounted for in a most straightforward way. This can be achieved via the fourcomponent formulation applying original Dirac formalism with almost no approximations. Due to a considerable software development effort in recent years, two of those quantum chemical ...

On Theoretical Problems in Synthesis of Superheavy Elements

Predictions and structure studies of superheavy elements (SHE) have been made, since the establishment of the nuclear shell model[1]. Especially in the last decade, elaborate investigations have been performed of shell correction energy and thereby of a possible location of the superheavy island in the nuclear chart. Furthermore, not only about the center of the island, but also about stability...
