Calculations of the probability densities and energies for N α-cluster nuclei 12 C (3α), 16 O (4α), 20 Ne (5α), 24 Mg (6α), 28 Si (7α) and for nuclear molecules 9 Be (α + n + α), 10 Be (α + n + n + α), were performed by the Feynman’s continual integrals method using parallel computing based on NVIDIA CUDA technology. New effective method for the solution of the hyperradial equations with cubic splines approximation is proposed and tested for exactly solvable 4-body system.
