摘要：

The octupole deformations and other ground state properties of even-even Rn, Th and U isotopes are investigated systematically within the framework of the reflection asymmetric relativistic mean field （RAS-RMF） model. The calculation results reproduce the binding energies and the quadrupole deformations well. The calculation results indicate these nuclei at ground states evolve from nearly-spherical （N=130） shape to quadrupole deformation shape with the increase of the neutron number. It is also found that among the Rn isotopes, only;Rn are octupole deformed and the octupole deformations for them are small. However, more nuclei （N■134-148） in Th and U isotopes are oetupole deformed and the octupole deformations for some of them are significant （|β;|～0.1 or even larger）.
