Sažetak

In variational calculation, we have obtained the binding energy of helium 3 dimer in two dimensions. The existence of one bound State, with the binding energy -0.014 mK, has been definitively found. Also, the existence of a binding state of helium 3 trimer having spin -1/2 with the energy below -0.0057 mK is indicated. This re-opens the question of the existence of the gas phase of many helium 3 atoms on the surface of superfluid helium 4.
