Abstract：
A discussion on the energy spectra and E2 transition rates of the even-even Xe isotopes with A=116 to 132 is carried out in the framework of neutronproton Interacting Boson Model.With the quadrupole interactions among like coherent nucleon pairs S and D being taken into account,the staggering phenomenon in the quasi-γ bands of these nuclei are improved. The calculated results of the low-lyingenergy levels agree with the experimrntal data quite well.
