DESCRIPTION:An important aspect for understanding the structure of nuclei 
 far from stability relies on our ability to be able to explain the evoluti
 on of collectivity with proton and neutron number. The region that lies ju
 st above the Z=50 closed shell in the vicinity of N=Z exhibits interesting
  collective properties of quadrupole and octupole character.\n\nThe strong
 est octupole collectivity has been predicted for the very light Xe and Ba 
 isotopes with  N ≈ Z ≈ 56. Octupole transition probabilities have bee
 n determined for the nucleus 114Xe\, being the deduced B(E3) transition m
 atrix elements for the 3− --> 0+ and 5− --> 2+ transitions\, 77(27
 ) and 68(17) W.u. respectively\, i.e.\, about the largest measured transit
 ion moments hitherto.\n\nWith the present experiment\, we aimed to address
  specific aspects of the collectivity development when approaching the N=Z
  line in even lighter Xe isotopes by performing a precise lifetime measure
 ment of the 5- state in 112Xe\, which theoretically is expected to prese
 nt a larger octupole collectivity than 114Xe. In addition\, we investigat
 e the quadrupole degree of freedom through the lifetime of the 2+ and 4+
  measured for the first time.\n\nhttps://indico.ific.uv.es/event/5994/
