Abstract
We study for the first time the internal structure of through the -delayed -ray spectroscopy of . The very neutron-rich nuclei with and were produced by the in-flight fission of beams at the Radioactive Isotope Beam Factory, RIKEN. The half-life and spin-parity of are reported as ms and , respectively. In addition to the excited states of produced by the -decay branch, the -delayed one-neutron and two-neutron emission branches were also established. By identifying the first and excited states of , we found that Te isotopes persist in their vibrator character with . We discuss the distinctive features manifest in this region revealed in pairs of isotopes with the same neutron holes and particles with respect to .
