Sažetak
We carry out a comprehensive study of the binding of two helium atoms in unrestricted and, in particular, in restricted geometries in both two and three dimensions. Besides the well known binding of the helium 4 dimer in unrestricted geometry in two and three dimensions, we also find weakly bound states of teh helium 3 - helium 4 molecule and helium 3 dimer in 2 dimensions. Furthermore, any combination of two helium 4 or helium 3 atoms can form a molecule if their motion is sufficiently confined. Our calculations are carried out by numerically solving the Schroedinger equation as well as by constructing a suitable variational wave function.
