Abstract
The manifestation of SU(4) symmetry within an interacting boson model including particle-like and hole-like pi- and v-bosons is shown for Li ght nuclei around the Z = N = 8 shell. We also present a consistent de scription of the particle-hole (intruder spin or I spin) multiplets in the Extended Interacting Boson Model (EIBM) and of pi-nu (F spin) mul tiplets in the IBM-2 as a breaking of this SU(4) symmetry.
