摘要

To describe obvious intruder states and nonzero quadrupole moments of gamma-soft nuclei such as Pt-194, a rotor extension plus intruder configuration mixing with 2n-particle and 2n-hole configurations from n = 0 up to n - infinity in the O(6) (gamma-unstable) limit of the interacting boson model is proposed. It is shown that the configuration mixing scheme keeps the lower part of the gamma-unstable spectrum unchanged and generates the intruder states due to the mixing. It is further shown that almost all low-lying levels below 2.17 MeV in Pt-194 can be well described by modifying the O(6) quadrupole-quadrupole interaction into an exponential form. The third-order term needed for a rotor realization in the interacting boson model seems necessary to produce nonzero quadrupole moments with the correct sign.
