Coulex of ¹⁴²Xe — •Corinna Henrich for the IS548-MINIBALL collaboration — TU Darmstadt, Darmstadt, Germany

The low-lying nuclear structure of ¹⁴²Xe was probed in a "safe" Coulomb excitation experiment at HIE-ISOLDE (CERN). While beam and target nuclei were detected utilizing the segmented Silicon detector array C-REX, the MINIBALL spectrometer was used to detect the emitted gamma rays in coincidence. ¹⁴²Xe is located north east of the doubly-magic nucleus ¹³²Sn and in the proximity of ¹⁴⁴Ba. The latter shows the largest octupole collectivity in the region. Therefore, this work aims to follow the evolution of quadrupole and octupole collectivity by means of spectroscopic quadrupole moments and reduced transition probabilities.

This work is supported by BMBF under contract 05P15RDCIA and 05P18RDCIA, by the EU under contract ENSAR 262010 and by ISOLDE.
