The even–even nucleus 142Xe lies north-east of the doubly magic 132Sn
on the neutron-rich side of the nuclear chart. In order to gain further
information on the octupole collectivity and the evolution of quadrupole
collectivity in this region, a “safe” Coulomb excitation experiment was carried out at the new HIE-ISOLDE facility (CERN) at the end of 2016. As
the gamma-ray detector the Miniball spectrometer was used. Beam and
target nuclei were detected using C-REX, i.e. an array of segmented Si
detectors, covering forward as well as backward angles in the laboratory
frame.
