Test of Wigner's Spin-Isospin Symmetry from Double Binding Energy Differences
P. Van Isacker1, D.D. Warner, D.S. Brenner

It is shown that the anomalously large double binding energy differences for even-even N = Z nuclei are a consequence of Wigner's SU(4) symmetry. These, and similar quantities for odd-mass and odd-odd nuclei, provide a simple and distinct signature of this symmetry in N≃Z nuclei.
