Times Cited Count:167 Percentile:97.31(Physics, Multidisciplinary)An isotope of the 113th element, 113, was produced in a nuclear reaction with a Zn beam on a Bi target. We observed six consecutive decays following the implantation of a heavy particle in nearly the same position in the semiconductor detector, in extremely low background condition. The fifth and sixth decays are fully consistent with the sequential decays of Db and Lr both in decay energies and decay times. This indicates that the present decay chain consisted of 113, Rg (Z = 111), Mt (Z = 109), Bh (Z = 107), Db (Z = 105), and Lr (Z = 103) with firm connections. This result, together with previously reported results from 2004 and 2007, conclusively leads the unambiguous production and identification of the isotope 113, of the 113th element.

Operator supporting systems in JOYO have been developed for stable operation itself and credible operation of future FBR. JOYCAT which applies AI technique is one of these systems. The inference engine for diagnosis and the knowledge base of secondary cooling system were developed, and then the verification test of JOYCAT was conducted with coupling with JOYO operator training simulator in FY1986. By generating some malfunctions in the simulator, the function (decision of first hit alarm, choosing of first operation and sequence monitoring) of JOYCAT was tested in FY1987. Through the development works, knowledge and experience for means to construct the knowledge base, to verify function of this system and to improve the function for highly advanced system were obtained. Considering these experiences, the knowledge base will be expanded for other plant systems and the diagnosis will be further improved. After the verification test with the simulator will be carried out repeatedly to confirm credibility. This system will be equipped JOYO by 1990.

We performed the experiment to synthesize an isotope of the element 113 produced by a Bi(Zn,n)113 reaction using a gas-filled recoil ion separator (GARIS) at RIKEN. Two decay chains were observed, and assigned to those originating from an isotope 113. Both chains were connected into the previously known decays of Bh and Db via previously unknown decays of 113, Rg, and Mt. Although the Bh was known nuclide, a number of atoms reported so far was limited. In order to study more precise decay property of the Bh, we performed the direct production of Bh by the Cm(Na,5n)Bh reaction. In this experiment, the Bh was clearly identified from the correlation of the nuclide, Db. The obtained decay properties of Bh and Db are consistent with those observed in the 113 chain, which provided further confirmation of the discovery of 113.
