We present recent results from our investigation of low-lying quadrupole collectivity in the semi-magic N=82 nucleus ¹³⁶Xe. An experiment was performed at the Legnaro National Laboratory employing the AGATA demonstrator. Level-lifetimes and B(E2, 0₁⁺→2_i⁺)-values were determined from Coulomb excitation and by the continuous-angle DSA method exploiting AGATA’s position resolution. 2_i⁺ - states up to i=7 were excited and analyzed. This work was supported by the BMBF under grants No. 05P09RDFN4 and 06P12RDFN8.
