Graphical approach to correlations in high-spin systems

We present a graphical technique for generating and indexing spin monomials of high-spin systems. The procedure consists of developing a graph with at most n line segments from each node in a given row to the one immediately lower, where n is the multiplicity of single-particle spin function. The pa ths lead to monomials with definite M values at each node. This technique h as been used to generate and diagonalize the model spin Hamiltonian. (C) 19 99 John Wiley & Sons, Inc.
