On details of implementation of Orthogonality Condition Model with   dynamic exclusion of forbidden two-body states for description of 12C as   system of three clusters
  3-alpha cluster model with dynamic exclusion of forbidden by Pauli principle two-body states is studied. We implement this model by step-by-step inclusion of components of prescribed by the model Hamiltonian, carefully studying intermediate results, and behavior of obtained solutions. A few qualified modifications are introduced in order to significantly simplify necessary computational schema.
