[RIBF-ULIC-miniWS-005] Isomer Spectroscopy during the New Isotope Search Experiment using Uranium Beam

Thursday 8 Sept 2011, 09:30 → 18:00 Asia/Tokyo

Nishina Hall

Shunji Nishimura (RIKEN), Toshiyuki Sumikama (Tokyo University of Science)

Isomer spectroscopy is important not only for the confirmation of a particle identification of in- flight fragments but also for a study of an exotic structure of very neutron-rich nuclei. New isotope experiment using Uranium beam at this autumn is a good opportunity also for new isomer search in middle and heavy neutron-rich nuclei. Germanium detectors will surround a total E detector to measure gamma rays from isomeric state produced via in-flight fission reaction. Physics cases of isomer spectroscopy in neutron-rich region will be discussed in this workshop.
