Energy spectrum of the equal spin-spin interactions Hamiltonian

摘要

The energy spectrum of eigenvalues of the equal spin-spin interactions (ESSI)Hamiltonian has been found. The obtained spectrum is free from limitationsimposed on number of spins and parameters of the ESSI Hamiltonian. This modelcan be used for consideration of spin dynamics of mesoscopic systems andmolecules with large number of nuclei spins.
