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.

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.

We report the plan and current status of development for software used on high-intensity chopper spectrometer, 4SEASONS, and Cold Neutron Disk-Chopper Spectrometer, CNDCS, at Materials and Life Science Facility(MLF), J-PARC. We begin to design software packages based on many required functions for performing experiments and analysis, for example control spectrometer system (data acquisition, devices), suggestion of experiment conditions, visualization and so on. This project progresses with software company. On the other hand, we started to collaborate with Korean group about the development of analysis software for inelastic scattering. In this presentation, we will present the current status and plan for software development including collaboration with Korean group.

Recently discovered iron-arsenide new superconductor has attracted considerable attraction. Within a few months the transition temperature (
) exceeded 50 K in some related compounds, and the possible novel physics as well as higher- are expected. At the early stage, calculations of phonon properties appeared and suggested that the superconductivity in these materials are not phonon mediated. However, the experimental verification is crucial. We carried out inelastic X-ray scattering on some powder as well as single samples, and found pronounced softening of the Fe-As modes compared to LDA-based phonon calculations. However, further investigation on single crystals showed the spectra are found to agree much better with calculations of the magnetic parent material, which has orthorhombic symmetry, than those using a tetragonal structure like the real superconducting compounds.
