Calculations of the probability densities and energies of the ground states for -cluster nuclei
C (3
),
O (4
),
Ne (
),
Mg (
),
Si (
) and for nuclear molecules
Be (
),
Be (
),
B (
),
C (
),
B (
),
C (
) were performed by the Feynman Path Integral method using parallel computing based on NVIDIA CUDA technology. In addition,
C (3
) was considered in three-body hyperspherical harmonics formalism with a new effective method of solving hyperradial equation using cubic spline interpolation. The spatial structures of the ground states of
C and
O correspond to simple geometric shapes, a regular triangle and a tetrahedron, respectively, with wide
-cluster clouds in their vertices. The
Mg nucleus has the shape of a pair of equal regular triangles with wide
-cluster clouds in their vertices as well. The nuclei
Be,
Be,
B,
C,
B,
C have molecular structure with valence neutrons and/or protons between two
-clusters.
