结果表明，偶-偶{italN}={italZ}核的超大双束缚能差是Wigner SU（4）对称性的结果.这些以及奇质量核和奇-奇核的类似量，为{italN}{congruent}{italZ}核的这种对称性提供了一个简单而独特的特征。
It is shown that the anomalously large double binding energy differences for even-even {ital N}={ital 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 {ital N}{congruent}{ital Z} nuclei.
