Ananikian N. S. , Lusiniants R. R. , Oganessyan K. A.
The Feigenbaum exponents a and «5 for the tree-site antiferromagnetic Ising spin model on the Husimi tree are calculated. It is shown that the numerical values of these exponents for the real statistical system coincide with the famous universal Feigenbaum exponents with high accuracy. The quantitative description of the transition from order to chaos is also obtained. © 1995 American Institute of Physics.
