Sažetak
It is shown that binding energy of helium 4 dimer for the same class of potentials depends on used set of the potential parameters. The existence of one energy excited state of dimer which is related to one node of the radial wave function is also proved for all used potentials. Excited state energy is about -0.3 mK. The expectation value of the internuclear distance is about 49 Angstr. in the ground state and 679 Angstr. in the excited state.
