Abstract :
The manifestation of SU(4) symmetry within an interacting boson model including particle-like and hole-like π- and ν-bosons is shown for light nuclei around the Z=N=8 shell. We also present a consistent description of the particle-hole (intruder spin or I spin) multiplets in the Extended Interacting Boson Model (EIBM) and of π-ν (F spin) multiplets in the IBM-2 as a breaking of this SU(4) symmetry.
