In intense laser fields, molecules are decomposed into fragments through a number of competing dissociative ionization pathways. We investigate the dissociative ionization dynamics of ethanol in intense laser fields with photoelectron-photoion coincidence momentum imaging. The channel-specific photoelectron spectra reveal the electronic states prepared just after ionization, depending both on the decomposition pathways and on the temporal profile of laser pulses.

Liquid drop model is a representative model to describe binding energy and size of nuclei. This model is well reproduces bulk properties of nuclei even in current studies on nuclei. In this presentation, we investigate nuclear symmetry energy and nuclear surface energy by using the nuclear liquid drop model with some higher-order terms. The coefficients of these term are determined so as to reproduce measured nuclear masses of approximately 2200 nuclides. From this analysis we find an indication that the fourth-order terms of the symmetry energy is required and the curvature term of it is negligible. Regarding a mass-number dependency on nuclear radius, we also find that the dependency of lighter nuclei (typically with mass number, 
) is larger than that of heavier nuclei.

The S=1/2 distorted diamond chain is investigated by the density matrix renormalization group and the numerical exact diagonalization. We found that an incommensurate long-range order is induced by the external magnetic field above the 1/3 magnetization plateau. We using this result theoretically explain the field induced incommensurate order observed in the azurite.

Tungsten is one of the candidates for the divertor material of ITER because of its low retention and low hydrogen inventory. However, it is a problem that tungsten ions accumulated in a core plasma emit intense radiation and cool the plasma. For preparation of investigating the mechanism of the tungsten ion accumulation, Vaccum Ultra Violet (VUV) lines emitted from tungsten ions are identified. A VUV spectrum from a JT-60U plasma (
keV) is observed with a flat-field grazing-incidence spectrometer. The observed spectrum is compared with a theoretical spectrum calculated with Flexible Atomic Code. It is found that the observed peaks around 3 nm are due to transitions between 
levels of W
(
), and that those around 5, 6 and 13 nm are due to transitions between 
levels of W (
). It is believed that the former lines are useful to diagnose the tungsten ion accumulation in a high-temperature (
10 keV) plasma of ITER.

FeSrYCuO is known as the BaYCuO related super conducting compound with the substitution of the Fe for Cu, only when it is annealed in reduced atmosphere and subsequently in oxidized atmosphere. In this study, we have performed neutron powder diffraction of FeSrYCuO to investigate the magnetic disorder-ordering mechanism. No magnetic reflection was observed even below the magnetic transition temperature. This result indicated that the material has not long-range magnetic-ordering.

A guiding-centre fundamental 1-form whose symplectic part does not include the EB term is derived by the Lie-transform perturbation method. Since the symplectic part of the derived 1-form is the same as the standard one without the strong EB flow formally, it yields the standard Lagrange and Poisson brackets. Therefore the guiding-centre Hamilton equations also keep the standard form. The guiding-centre Hamiltonian is rather complicated compared to the previous ones. However, it is possible to simplify the Hamiltonian in localised transport barrier region like the tokamak H-mode edge.
