چکیده انگلیسی
Using the multiconfiguration Dirac-Fock method, calculations for the lowest 62 levels of the ([Ar] 3d10)4s24p5, ([Ar] 3d10)4s24p34d2, ([Ar] 3d10)4s24p44d, ([Ar] 3d10)4s4p6, and ([Ar] 3d10)4s4p54d configurations are performed for the bromine isoelectronic sequence La XXIII-Dy XXXII, W XL. Results of energy levels, lifetimes, wavelengths, and electric dipole, magnetic dipole, electric quadrupole, and magnetic quadrupole radiative rates are presented. In order to assess the accuracy of results, independent calculations for W XL have been carried out using the many-body perturbation theory (MBPT) method. Comparisons are made with available theoretical results from other calculations and the observed values of the Atomic Spectra Database of the National Institute of Standards and Technology. Energy levels are estimated to be accurate to better than 1%, and radiative rates (and lifetimes) are accurate to better than 20% for a majority of strong transitions. These results should be useful in many applications of lanthanide ions related to broad area of research such as applied physics, laser physics and fusion science.
