I am a big fun of professor's Motobayashi talks and for what I´ve heard from other students this was one of the most awaited talks in the PASI. Motobayashi san showed the status of the new RIBF facility in RIKEN, the first new generation in RI beams.
Energetic heavy-ion beams are converted into intense RI beams via the projectile fragmentation of stable ions or the in-flight fission of uranium ions by the superconducting isotope separator. This upgrade will expand the knownledge of the nuclear chart to presently unreachable region (about 7,000 isotopes predicted but not known) mostly at the neutron rich side.
It is already in operation and the first measurenment was the doppler shifted gamma-ray for excited nuclei in flight. He also showed the production of 127Pd and 128Pd among other 45 new isotopes (Z=25-56) using in flight fission of 238U and the analysis to obtain beta decay half lives is in progress.

Thanks for your interest. Questions are welcome. Send mail to me (motobaya@riken.jp), since I already left Joao Pessoa (with regret).
