Sažetak
The general formulation of a technically advantageous method to find the ground state solution of the Schrödinger equation in configuration space for systems with the number of particles A greater than 4 is presented. The wave function is expanded in pair-correlated hyperspherical harmonics beyond the lowest-order approximation and then calculated in the Faddeev approach. A recent efficient recursive method to construct antisymmetric A-particle hyperspherical harmonics is used. The accuracy is tested for the bound-state energies of nuclei with A = 6 to 12 using the effective V4 potentials. The high quality of the obtained results becomes evident from a comparison with other approaches.
