Identification of deformed intruder states in semi-magic $$^{70}$$Ni

The neutron-rich isotope $$^{70}$$Ni was produced by multi-nucleon transfer reactions of $$^{70}$$Zn in the Argonne National Laboratory, and an in-beam $$gamma$$-ray experiment were performed using the GRETINA array. The $$2^+_2$$ and $$4^+_2$$ levels of $$^{70}$$Ni were observed for the first time. Those levels are regarded as large deformed states associated with proton excitation from the $$f_{7/2}$$ orbit because they cannot be reproduced by a shell-model calculation assuming a small valence space without $$f_{7/2}$$. A theoretical analysis based on the Monte Carlo shell model published in 2014 indicates that those levels corresponds to a prolate deformed band. The present result demonstrates the occurrence of shape coexistence in neutron-rich Ni isotopes other than a known case of $$^{68}$$Ni, and confirms the predictive power of the Monte Carlo shell-model calculation.

Lagrangian models for nuclear studies; Examples and applications

Arnold, D.*; Seibert, P.*; Nagai, Haruyasu; Wotawa, G.*; Skomorowski, P.*; Baumann-Stanzer, K.*; Polreich, E.*; Langer, M.*; Jones, A.*; Hort, M.*; et al.

Lagrangian Modeling of the Atmosphere, p.329 - 347, 2013/05

WSPEEDI uses a combination of non-hydrostatic mesoscale atmospheric model MM5 and Lagrangian particle dispersion model GEARN. MM5 is a community model having many users all over the world and is used for the official weather forecast by some countries. GEARN calculates the atmospheric dispersion of radionuclides by tracing the trajectories of a large number of marker particles discharged from a release point. Japan Atomic Energy Agency (JAEA) has been undertaking the task to assess the radiological dose to the public resulting from the Fukushima Daiichi Nuclear Power Plant accident by using both environmental monitoring data and computer simulation on the dispersion of radioactive materials in the environment. As the first step, the source term of radioactive materials discharged into the atmosphere was estimated. Then, by using the estimated source term, detailed analysis on the local atmospheric dispersion around the Fukushima Daiichi Nuclear Power Plant has been carried out.

Stability of non-stoichiometric clusters in the MA957 ODS ferrtic alloy

In our past work, the commercial ferrtic Oxide Dispersion Strengthened (ODS) alloy MA957 had at least two types of nanometer-sized oxide particles: non-stoichiometric Y-, Ti-, O-enriched clusters and Y$$_{2}$$Ti$$_{2}$$O$$_{7}$$ particles. The size of the non-stoichiometric clusters was much smaller than that of Y$$_{2}$$Ti$$_{2}$$O$$_{7}$$ particles and it was confirmed that the non-stoichiometric clusters possibly dominate the oxide dispersion strengthening. Therefore, this study dealt with the stability and evolution mechanisms of non-stoichiometric nanoclusters after the annealing (1473K $$times$$ 1h). This annealing condition was determined considering the actual condition of consolidation processes. After the annealing, most non-stoichiometric Y-, Ti-, O-enriched clusters were stable, but some clusters became Y$$_{2}$$Ti$$_{2}$$O$$_{7}$$ particles with increasing size. The diffusion of yttrium had an important role for the evolution of these oxides.

Tuning hydrogen production during oxide irradiation through surface grafting

Alam, M.*; Miserque, F.*; Taguchi, Mitsumasa; Boulanger, L.*; Renault, J. P.*

Journal of Materials Chemistry, 19(24), p.4261 - 4267, 2009/06

The production of molecular hydrogen in the radiolysis with TiO$$_{2}$$ grafted silica has been carefully studied using 10 MeV electrons. In all cases, H$$_{2}$$ yield increases linearly with absorbed dose. Under the irradiation it was observed that with the increasing number of titanium dioxide deposition cycle a decrease in dihydrogen production were observed. A faster decrease in dihydrogen production was observed with a very small amount of titanium dioxide deposition i.e with an average thickness of 0.1 nm as measured by XPS. The productions of H$$_{2}$$ were found to be decreased almost by 50 % with a TiO$$_{2}$$ thickness at around 1 nm.
