摘要：

General scaling rules for size versus energy are established for systems of one and two neutrons weakly bound to a heavier core. The mean square radius of the two-neutron halo in s-states diverges only logarithmically at small binding energy and is therefore asymptotically smaller than the corresponding one-neutron halo. They are of comparable size at about 200 keV for light nuclei. The limiting binding energy below which halos appear is estimated to be 2 MeV/A2/3.
