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 (No 101+ , Z=102). The wavelengths, logarithmic weighted oscillator strengths and transition probabilities of No 101+ 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.

Highlights

  • The developing technology requires precise knowledge of wavelengths, oscillator strengths, and transition probabilities for highly charged ions

  • This work has extended for transition parameters using mentioned high accuracy level structure data

  • The only basic formulas of multiconfiguration Hartree-Fock (MCHF) and multiconfiguration Dirac-Fock (MCDF) method have here mentioned for the brevity

Summary

INTRODUCTION

The developing technology requires precise knowledge of wavelengths, oscillator strengths, and transition probabilities for highly charged ions. It is great needs for interpretation of astrophysical spectra and atomic collision studies, the development of X-ray lasers and the diagnostics of fusion plasmas etc. The unique theoretical data for transition parameters of No101+ belongs to Jitrik and Bunge [4 and 5] They have published two papers about calculations using point-nucleus Dirac eigenfunctions which contains nl (n=1-26, l=0-25) levels with 1≤Z≤118. This lack has led to perform present work as a part of three, two, and one electron actinides investigation [7, 8, and 9] It is important the supporting theoretical data with experimental one. Correlation effects have been included in both methods
