Devi, V. Kota] Geometric aspects of the extended interacting boson model (gIBM) withs, d andg bosons are studied using coherent states. Algebraic expressions for the coherent state expectation values of various terms in the general gIBM Hamiltonian are derived in terms of the quadrupole and hexadecupole deformation variablesβ 2 andβ 4 and the asymmetry angleγ. These in turn are used to determine the equilibrium shape parameters (β 2 0 ,β 4 0 ,γ 0) in the seven dynamical symmetry limits of gIBM.
