Applications of Soft X-Ray Spectroscopy

For a general potential V (r), this spin-orbit coupling is given by: Hˆ 2 = 1 2m2c2 1 The aim of this paper is to test predictions of LS-coupling theory for the transitions within 3s2S-3p2P0 and 3p2P0-3d2D multiplets of singly ionized carbon. Must add a new term to the Hamiltonian operator, H s o = ∑ i = 1 N ε i M l i → · M s i → ε i = spin–orbit coupling constant, which increases as the atomic number increases. i. For low atomic numbers, one can use an approximation called the Russell-Saunders or L • S coupling. approximation is called LS coupling or Russell-Saunders coupling. The things which are coupled in this coupling are: 1. All the individual orbital angular momenta couple together to make ^L.

Here the residual electrostatic interaction refers to the term including electron-electron interaction after we employ the central field approximation to the Hamiltonian of the atom. LS or Russell-Saunders coupling is dominant for many transitions in the spectra of light elements. This is the case spin-orbit interaction in atomic Hamiltonian is more important than the Russell-Saunders or L-S Coupling For multi-electron atoms where the spin-orbit couplingis weak, it can be presumed that the orbital angular momenta of the individual electrons add to form a resultant orbital angular momentum L. Likewise, the individual spin angular momenta are presumed to couple to produce a resultant spin angular momentum S. Armstrong's method of relativistic description of atoms in LS coupling using the equivalent operator is developed.

Its form in terms of standard unit operators acting within a space of one shell is The various orientations of orbital angular momentum and spin give rise to the fine structure of atomic spectra. This is known as spin-orbit coupling or LS coupling since the total orbital angular momentum, $L$, of a group of electrons interacts with the total spin, $S$, of that group of electrons, following the vector model of angular momentum.
