The Electric Dipole Transitions of Hydrogen Like Nobelium

Abstract

It is an occasion to understand and test the methods for determination of atomic structure on hydrogen like ions especially with high atomic number, Z. Many studies such as interpretation of astrophysical spectra and atomic collision studies, the development of X-ray lasers etc. demand exact transition parameters data. This need is a reason of the present paper to support more precise atomic data of electric dipole transitions parameters for hydrogen like nobelium (No¹⁰¹⁺, Z=102). The wavelengths, logarithmic weighted oscillator strengths and transition probabilities of No¹⁰¹⁺ have been reproduced with relativistic multiconfiguration Hartree-Fock (MCHF) and fully relativistic multiconfiguration Dirac-Fock (MCDF) methods. The transitions between nl (n=1-9 and l=0-4) levels have been investigated in this work. The results of MCHF and MCDF methods have been compared with a unique theoretical work, because there has been neither theoretical nor experimental work in available literature.
