被引用回数：8 パーセンタイル：45.54(Multidisciplinary Sciences)Data on radiocesium concentrations and fluxes have been collected in rivers within 80 km of the FDNPP from June 2011, three months after the accident, to the present. That data is available on the web up to March 2017. These data are expected to be widely used for validation of the radiocaesium transport model, comparison between the FDNPP and Chernobyl accidents, influence on the health of residents, and evaluation of the effect of the environmental remediation measures in Fukushima. Therefore, these data set were provided in this data journal.

被引用回数：73 パーセンタイル：94.89(Engineering, Environmental)The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident released the largest quantity of radiocesium into the environment since Chernobyl. Here, we show for the first time, how redistribution of radiocesium by river and watershed-scale hydrological processes in Fukushima is driving localized decline in terrestrial dose rates in populated areas. The rate of Fukushima recovery greatly exceeds initial post-disaster expectations and indicates that landscape-scale recovery from such large contamination events is highly dependent on local hydrological and land use controls.

被引用回数：11 パーセンタイル：74.44(Physics, Nuclear)The neutron-deficient mercury isotopes serve as a classical example of shape coexistence, whereby at low energy near-degenerate nuclear states characterized by different shapes appear. The electromagnetic structure of even-mass 
Hg isotopes was studied using safe-energy Coulomb excitation of neutron-deficient mercury beams delivered by the REX-ISOLDE facility at CERN. The population of 0
, 2, and 4
states was observed in all nuclei under study. Reduced 
matrix elements coupling populated yrast and non-yrast states were extracted, including their relative signs. These are a sensitive probe of shape coexistence and may be used to validate nuclear models. The experimental results are discussed in terms of mixing of two different configurations and are compared with three different model calculations: the Beyond Mean Field model, the Interacting Boson Model with configuration mixing and the General Bohr Hamiltonian. Partial agreement with experiment was observed, hinting to missing ingredients in the theoretical descriptions.

Rn were studied by means of low-energy Coulomb excitation at REX-ISOLDE, CERN. The electric-quadrupole (E2) matrix elements connecting the first excited 2
to the ground state of these nuclei was extracted, which permits to determine the collectivity of these isotopes, which in both cases is deduced to be weak, as expected from the low-lying level-energy scheme. Comparisons were also made with beyond-mean-field model calculations and the magnitude of the transitional quadrupole moments are well reproduced.

被引用回数：29 パーセンタイル：85.36(Astronomy & Astrophysics)Single-neutron states in Zn have been populated using the reaction Zn(d,p) at REX-Isolde, CERN. The analysis reveals that the lowest excited states in Zn lie at approximately 1 MeV, and involve neutron orbits above the N=50 shell gap. A 5/2
configuration was assigned to the 983-keV state. Comparison with large-scale shell model calculations supports a robust neutron N=50 shell closure for Ni. These data constitute an important step towards the understanding the magicity of Ni and the structure of nuclei in the region.

Kr has been determined from reported and E(2
) values. This is in contrast to the sudden onset in even-even Zr, Mo, and Sr isotopes. Our objective was to complete the systematics by determining the value in Kr, which was produced by cold-neutron-induced fission of 
U. The lifetime of the 2 state in Kr was measured via the electronic 
timing technique using the EXILL and FATIMA spectrometers. Based on the measured mean lifetime of 
= 15(10) ps, the value of 13
W.u. in Kr is determined for the first time and the smooth onset of deformation in the even-even Kr isotopes beyond neutron number N=50 is confirmed.

Single-neutron states in the 
= 49 isotope Zn were populated in the Zn(d,p)Zn transfer reaction at REX-ISOLDE, CERN. The combined detection of protons ejected in the reaction and of 
rays emitted by Zn permitted the identification of the lowest-lying 5/2 and 1/2 excited states. The analysis of proton angular distributions links these states to a significant amount of single-particle strength around 1 MeV, and specifically to the 
d
and s
neutron orbits, which lie above the = 50 neutron shell gap. Comparison with large-scale-shell-model calculations supports a robust = 50 shell-closure for Ni. These data constitute a considerable step towards the understanding of the magicity of Ni and of the structure of isotopes in the region.
