Lifetimes in ^128,130Te extracted via the Doppler-shift attenuation method using pγ coincidences

To study the E2 strength around the semi-magic Sn isotopes, existing data for the Te isotopes were compiled. Since the information on level lifetimes in ¹²⁸Te and ¹³⁰Te is scarce, two pγ-coincidence experiments were performed using the Doppler-shift attenuation method (DSAM) at the SONIC rate at HORUS setup in Cologne. Nuclear-level lifetimes were extracted and feeding contributions could be excluded by particle energy gates in the spectra from the new version of the silicon detector array SONIC. By determining γ-decay branching ratios and B(E2) transition strengths, systematics in the Te isotopes were examined. This contribution presents the experimental setup as well as preliminary results and discusses the systematics in the Te isotopes.
