T-dependence and anisotropy of Knight shift and spin-lattice relaxation time T1 of In-NMR have been determined in heavy fermion superconductor CeIrIn. Knight shift and T1 show a strong anisotropy. Knight shift versus static susceptibility plot is non-linear at low temperatures, indicating that the hyperfine coupling depends on temperature. The origin of hyperfine interaction and anisotropy of spin fluctuations will be discussed.

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.

We performed neutron inelastic scattering experiments in NaFe(CO)(HO) that consists of two-leg spin ladders of Fe
ions. We observed sharp magnetic excitation peaks around 
3.5 meV and 5.3 meV. This result shows that the magnetic excitations originate from almost isolated dimers, indicating that the interaction along the leg direction is negligibly small.

Chromatic and spherical aberrations are hindrance in a development of acceleration lens system to form the nanobeam with 1 MeV ion beam. However, chromatic and spherical aberrations are hindrance to form the nanobeam. Optics simulations were carried out to show that a combination of acceleration lenses and deceleration lenses is effective to reduce chromatic and spherical aberrations in the acceleration lens system. As a result, the deceleration energy of 15 keV for the 46 keV hydrogen molecule ion beam enabled us to reduce the chromatic aberration coefficient by 26 % and the spherical aberration coefficient by 17 %, and the beam current increased by 27 %.

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.
