Abstract By analysing the energy spectrum and E2 transition branching ratios, we show that the E(5) symmetry predictions agree well with the experimental data of nucleus ¹³⁰Xe. Compared the calculated results with those in the framework of the interacting boson model, it is found that the nucleus ¹³⁰Xe is definitely a nucleus in the transitional region from U(5) to O(6) symmetry. ¹³⁰Xe is then another empirical evidence of the nucleus with E(5) symmetry.
