Excited states in 124Xe have been studied via the 12C(124Xe,124Xe*) Coulomb excitation reaction. Relative cross‐sections have been determined from the γ‐ray yields observed with Gammasphere. The E2 strengths between the low‐spin states in 124Xe have been determined. The results clearly show the realization of the O(5) symmetry even for the off‐yrast states with high τ, while the O(6) symmetry seems to be already broken.
