Times Cited Count:45 Percentile:96.7(Physics, Multidisciplinary)A quasifree (,) experiment was performed to study the structure of the Borromean nucleus B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for and orbitals, and a surprisingly small percentage of 9(2)% was determined for . Our finding of such a small component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in B. The present work gives the smallest - or -orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of or orbitals is not a prerequisite for the occurrence of a neutron halo.

Times Cited Count:5 Percentile:38.03(Physics, Nuclear)High-spin states of Pt have been reinvestigated using the Yb(O, 4) reaction at a beam energy of 88 MeV. The previously known positive parity band associated with the ( being or ) configuration has been revised and extended significantly. A new negative parity band has been established and proposed to be based on the configuration. Possible structure evolution of the yrast line from predominantly vibrational to rotational with increasing spin is discussed with the help of E over spin curves. Additionally, calculations of Total Routhian surfaces have been performed to investigate the band properties.

Times Cited Count:101 Percentile:94.61(Ecology)Radionuclide impact of the Fukushima Dai-ichi Nuclear Power Plant accident on the distribution of radionuclides in seawater of the NW Pacific Ocean is compared with global fallout from atmospheric tests of nuclear weapons. Surface and water column seawater samples collected during the international expedition in June 2011 were analyzed for Cs, Cs, I and H. The Cs, I and H levels in surface seawater offshore Fukushima varied between 0.002-3.5 Bq/L, 0.01-0.8 Bq/L, and 0.05-0.15 Bq/L, respectively. At the sampling site about 40 km from the coast, where all three radionuclides were analyzed, the Fukushima impact on the levels of these three radionuclides represent an increase above the global fallout background by factors of about 1000, 30 and 3, respectively. The water column data indicate that the transport of Fukushima-derived radionuclides downward to the depth of 300 m has already occurred. The observed Cs levels in surface waters and in the water column are in reasonable agreement with predictions obtained from the Ocean General Circulation Model, which indicates that the radionuclides have been transported from the Fukushima coast eastward. Due to a suitable residence time in the ocean, Fukushima-derived radionuclides will provide useful tracers for isotope oceanography studies on the transport of water masses in the NW Pacific Ocean.

Low-spin signature inversion is revealed in the 7/2[503] band. The inversion can be interpreted as a configuration change from the 7/2[503] orbital to the 7/2[514] orbital with increasing spin, which is supported by a theoretical calculation of the semi-classical Donau and Frauendorf approach.

Times Cited Count:9 Percentile:49.7(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

High-spin states in Re are investigated via in-beam -ray spectroscopic method and coincidence relationships are analysed. A new band is identified due to its spectroscopic connection with the known band. This band is proposed to be the ground-state band built on the configuration in view of the low-lying intrinsic states in neighbouring odd-mass nuclei. It is in particular interesting that the new band exhibits a phenomenon of low-spin signature inversion, providing a new situation for theoretical investigations.

A rotational band built on the configuration with oblate deformation has been established for Tl. Based on the structure systematics of the oblate bands in heavier odd-odd Tl nuclei, we have tentatively proposed spin values for the new band in Tl. The new oblate band shows low-spin signature inversion, and it can be interpreted qualitatively by the two-quasiparticle plus rotor model including a -dependent - residual interaction.
