Times Cited Count:0 Percentile:0.04(Physics, Nuclear)The first prompt in-beam -ray spectroscopy of a superheavy element, Rf, has been performed successfully. A development of an intense isotopically enriched Ti beam using the MIVOC method enabled us to perform this experiment. A rotational band up to a spin of 20 has been discovered in Rf, and its moment of inertia has been extracted. These data suggest that there is no evidence of a significant deformed shell gap at = 104.

Times Cited Count:58 Percentile:88.75(Physics, Multidisciplinary)Rotational band structure of the =104 nucleus Rf has been observed for the first time using an in-beam -ray spectroscopic technique. This nucleus is the heaviest among the nuclei whose rotational band structure has ever been observed. Thus, the present result provides valuable information on the single-particle shell structure and pairing interaction in the heaviest extreme of nuclei. The deduced moment of inertia indicates that there is no deformed shell gap at =104, which is predicted in a number of current self-consistent mean-field models.

Seaborgium isotopes were produced in the fusion reaction Si + U as evaporation residues (ERs), and the cross sections were determined. The experiment was carried out at GSI in Darmstadt, Germany. At the center-of-mass energy of E= 144 MeV, three decay chains starting from Sg were observed, and the corresponding ER cross section was determined to be 67 pb. At the sub-barrier energy of E= 133 MeV, three spontaneous fission events of a new isotope Sg were detected. The cross section was 10 pb. The half-life of Sg was determined to be 120 ms. The ER cross sections were compared with a statistical model calculation. In the fusion process, the coupled channel calculation taking into account the prolate deformation of U was adopted to determine the capture cross section. The calculated capture cross section agrees well with the fission cross section of Si + U obtained at the JAEA tandem accelerator. The measured cross section of Sg at the sub-barrier energy is factor 10 larger than the calculation based on the one-dimensional model in the fusion process, showing the fusion enhancement caused by the deformation of U. However, disagreement with the calculation suggests the presence of quasi-fission channel. At the above barrier energy of E = 144 MeV, the measured cross section is well reproduced by the calculation. This means that the interaction of Si at the equotorial side of U has advantage on the fusion process.

Times Cited Count:12 Percentile:59.13(Physics, Nuclear)Decay properties of Ra and Ra were invesigated by - spectroscopy. The nculei were produced by the fusion raction Er(Ca,n)Ra and decay daughter of Th produced by Er(Ti,3n). The evaporation residues were separated in flight by the velocity filter SHIP and the particle and ray were detected by silocon detectors and Ge detectors, respectively, located at the focal plane. In this experiments we found the followings. (1) The decay of Ra popultaing the excitated sates in Rn was coincided with the decay. From this data, we have newly assigned spins and parities for the three levels in Rn. (2) We have firstly observed the transition from the 8 isomeric state in Ra to the 8 isomeric state in Rn. The hindrace factor in this transition was determined to be 1.0, confirming that these levels have same spins.
