Description
Multinucleon transfer reactions are known to provide a useful method of populating
neutron-rich nuclei in gamma-ray spectroscopy experiments. Recent theoretical
calculations have suggested that such reactions could also be used to produce neutron-
deficient nuclei, but this has not been properly tested in experiments. The calculations
suggest that it may be possible to produce the neutron-deficient Z=54 xenon nuclei with
reasonable cross sections. These nuclei are of considerable interest due to their
propensity to develop octupole correlations heading towards N=Z. Here, we propose an
experiment to study the level schemes of the neutron-deficient xenon isotopes 110,112Xe
to further study the evolution of octupole correlations. In the experiment we will also
study the production yields of neutron-deficient nuclei above 100Sn with multinucleon 50
transfer reactions. We will use a beam of 58Ni at 316 MeV on a thin 112Sn target. The 28 50
beam-like reaction products will be identified using the PRISMA spectrometer, and the prompt decays of excited states will be measured using AGATA. To perform this measurement, we request 14 days of beam time.
