After the confirmation of the generation of the Compton backscattered X-rays with Nd:YAG laser and 150 MeV electron beam pulses at last fiscal year, we make some improvements for increase the generated X-ray flux. As one of them, we are developing the laser pulse compression with the stimulated Brillouin scattering (SBS) to obtain a high peak intensity of the Nd:YAG laser. As the SBS medium, we adopt a liquid fluorocarbon which has well achievements for the pulse compression at ILE at Osaka University. We aim the compressed pulse duration to be less than 1 ns. On this meeting we show the present status of the SBS pulse compression system for the Compton backscattering. In addition, we present the recent result of the Compton backscattering experiment without the laser compression technique.

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.

We have developed a new method to measure lifetime of long-lived isomers populated through the 
decay, using a total absorption detector. Using this method, we have determined lifetime of the K isomers in 
Gd and 
Gd for the first time. The short-lived neutron-rich nuclei Eu and Eu were produced and mass-separated by the on-line isotope separator (ISOL) at JAEA tandem accelerator facility. Beta- and 
rays emitted by the decay of Eu were total-absorbed by the detector, and all the events were recorded with time stamps. This method enabled us to determine lifetime of the isomers with more than 100-
s lifetime.

In this work, we demonstrate the irradiation effect of laser accelerated protons induced on human lung cancer cells. In-vitro A549 cells are irradiated with a proton dose of 20 Gy, resulting in a distinct formation of -H2AX foci as an indicator of DNA double-strand breaks. This is the first result showing that laser-driven ion beams can generate a lethal effect on cancer cells.

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.

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.
