چکیده

Abstract The multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction methods are used to provide excitation energies, lifetimes, radiative transition data for the 604 (699, 702, 704, 699) lowest levels of 3 s 2 p , d 4 f 5 configurations in Cr xi (Mn xii Fe xiii Co xiv Ni xv Cu xvi Zn xvii ). Previous line identifications EUV X-ray wavelength ranges reviewed by comprehensively comparing MCDHF theoretical results with available experimental data. Many recent lines confirmed, several new these two ions proposed. A consistent atomic set spectroscopic accuracy is provided hundreds Si-like iron-group elements astrophysical interest, which values scarce. uncertainty estimation method suggested Kramida, applied comparison length velocity strength values, ranking correlation latter gauge dependency patterns strengths investigated.

Electron-ion recombination of Si IV forming Si III: Storage-ring measurement and multiconfiguration Dirac-Fock calculations

The electron-ion recombination rate coefficient for Si IV forming Si III was measured at the heavy-ion storage-ring TSR. The experimental electron-ion collision energy range of 0–186 eV encompassed the 2p6nln l dielectronic recombination DR resonances associated with 3s→nl core excitations, 2s2p63snln l resonances associated with 2s→nl n=3,4 core excitations, and 2p53snln l resonances associate...
