Gamma ray spectroscopy of N=126 neutron-rich nuclei

The experiment aims at measuring the energies of the unknown low-lying excited states of neutron-rich isotopes with N=126. These nuclei were be produced by multi-nucleon transfer reactions of 136Xe beam + 198Pt target at a beam energy of 7 MeV/u. The projectile-like fragments (PLF) were detected and isotopically identified by the VAMOS++ spectrometer and the complementary target-like fragment will be detected directly by another set of detectors (2nd arm of VAMOS++). The discrete prompt and delayed gamma rays in coincidence from the excited states of the nuclei of interest will be measured using the AGATA array having 13 triple clusters placed around the target position and 4 EXOGAM Ge detectors placed around the implantation position of the 2nd arm, respectively.
