Studies in Fuzziness and Soft Computing way by means of diagrams. The evaluation of diagrams will be considered in detail, and we shall formulate general rules for their evaluation. We shall also discuss the separation of the diagrams into radial and spin-angular parts, taking advantage of the angular-momentum graphs developed in the earlier chapters.

Alexander Yazenin,Ilia Soldatenkooved fit to the experimental results can be obtained if the radial integrals appearing in the hyperfine Hamiltonian are treated as free parameters in a way similar to our treatment of the Slater parameters in the previous chapter.

Florentin Smarandache,Mumtaz Ali,Mohsin Khantem—in some detail. This example clearly demonstrates the usefulness of the graphical technique in dealing with angular-momentum problems of certain complexity. In a later chapter (Chap. 8)—after having studied the physical properties of atoms more systematically—we shall extend the technique further and apply it to general many-electron systems.

Fuzzy Multiple Attribute Decision Makingted form, however, and the problem is considerably simplified if we assume that the potential is spherically symmetric. The single-electron orbitais can then be written as a product of a radial function, a spherical harmonic and a spin function. This is the well-known central-field approximation.
