    "abstract": "We discuss the implications of partial dynamical SU(3) symmetry (PDS) for the\nstructure of the lowest K=0^{+} (K=0_2) collective excitation in deformed\nnuclei. We consider an interacting boson model Hamiltonian whose ground and\ngamma bands have good SU(3) symmetry while the K=0_2 band is mixed. It is shown\nthat the double-phonon components in the K=0_2 wave function arise from SU(3)\nadmixtures which, in turn, can be determined from absolute E2 rates connecting\nthe K=0_2 and ground bands. An explicit expression is derived for these\nadmixtures in terms of the ratio of K=0_2 and gamma bandhead energies. The\nSU(3) PDS predictions are compared with existing data and with broken-SU(3)\ncalculations for ^{168}Er.",
