不安定核セミナー開催(2015.9.2)
2015年8月7日 | 新着情報
A new generation radioactive isotope facility (RIBF) has started providing highest intensity neutron-rich nuclei using in-flight fission of a 345 MeV/nucleon 238U beam. Bringing together with high detection efficiency gamma-ray detectors (Euroball HPGe) and newly developed beta-counting system (WAS3ABi), harvest of decay properties for several hundreds of exotic nuclei has been conducted using the EURICA spectrometer [1-5].
My talk will describes the basis and recent progress made in beta-gamma spectroscopy and related topics of the rapid-neutron capture process (r process), sequence of neutron-capture and beta-decay processes. Future projects related to nuclear structure and nuclear astrophysics will be presented to discuss our perspective at RIBF.
