Abstract
A connection is established between an interacting boson model (IBM) t hat includes T = 1 bosons (IBM-3) and one that includes T = 0 as well as T = I bosons (IBM-4) The connection relies on an IBM-4, classificat ion that breaks Wigner's SU(4) symmetry. The resulting, generalized IB M-4 is relevant for studying the competition between T = 0 and T = 1 p airing in N similar to Z nuclei. Consequences for the pair structure i n self-conjugate nuclei are discussed.
