Abstract：
random one plus two–body hamiltonians invariant with respect to o(n_1)o(n_2)symmetry in the group–subgroup chains u(n )u(n_1)u(n_2)o(n_1)o(n_2)and u(n )o(n )o(n_1)o(n_2) of a variety of interacting boson models are used to investigate the probability of occurrence of a given(ω_1ω_2)irreducible representation(irrep)to be the ground state in even–even nuclei;[ω_1] and [ω_2] are symmetric irreps of o(n_1) and o(n_2) respectively. employing a 500 member random matrix ensemble for n boson systems (with n=10–25),it is found that for n_1,n_2≥3 the (ω_1ω_2)=(00) irrep occurs with～50% and (ω_1ω_2)=(n0) and (0n) irreps each with～25% probability. similarly,for n_1≥3,n_2=1,for even n the ω_1=0 occurs with～75% and ω_1=n with～25% probability and for odd n,ω_1=0 occurs with～50% and ω_1=1,n each with～25% probability. an extended hartree–bose mean–field analysis is used to explain all these results.
