## Nuclear Physics Around the Unitarity Limit

Author(s): Sebastian König, Harald W. Grießhammer, H.-W. Hammer, and U. van Kolck

Many features of three- and four-nucleon nuclei are well explained by a perturbative expansion around the unitarity limit. It is conjectured that this approach could work for heavier nuclei as well.
