An Algorithm of Constructing Potential Energy Surfaces for Nuclear Particle--Hole Excited Configurations

We discuss and illustrate a computer-designed algorithm allowing to construct the nuclear potential energy surfaces generated by a mean field Hamiltonian H(α) as functions of the ensemble of nuclear deformation variables α for multi-particle multi-hole excited configurations. The algorithm in question serves to eliminating the undesired effect of the so-called avoided crossing mechanism, a consequence of the well known property referred to as Landau-Zener non-crossing rule.
