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.

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.

Local structure analysis of 0.75BiFeO-0.25BaTiO solid solution was carried out by a synchrotron radiation X-ray pair-distribution function (PDF) method with the temperature range from room temperature to 900
C. The 0.75BiFeO-0.25BaTiO occurred two phase transitions. The average structure of changed from low-temperature rhombohedral structure to pseudo-cubic structure at 500C, but the local structure unchanged. The local structure changed at second phase transition from pseudo cubic structure to cubic structure at 800
C. The local structure of the pseudo-cubic phase can be reproduced not by the average cubic structure but by the distorted rhombohedral structure.

We have started the commissioning of the neutron scattering experiment instruments since May 2008 in MLF, J-PARC. Simultaneously, we have started the commissioning of the data acquisition and analysis software. Experimental users operate this software through the software framework which we have developed. The software framework was developed based on Python which is an object oriented script language. The system implemented with the software framework can seamlessly measure, analyze and visualize with some modules which are experimental control and data analysis. In this presentation, we report the process of the construction and the current status of the software.

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 %.
