The evolution of the collectivity of tellurium isotopes from mid-shell towards N=82 is currently based mainly on properties of the first excited 2+ states. To extend structural information in this isotopic chain, in particular with respect to the balance of microscopic, seniority-type and collective excitations, electric quadrupole transition strengths from 4+ states need to be considered. An experiment was performed to determine the 41+ lifetime of 132Te via the recoil-distance Doppler-shift method at the University of Cologne tandem accelerator. The isotope of interest was populated in the two neutron-transfer reaction 130Te(18O,16O)132Te^*. The E2 decay transition strength has been determined to be B(E2; 4+1→ 2+1) = 9.3(10) W.u. and compares favourably to shell model calculations.
