Hyperfine structures of transitions in ions of the radioactive lanthanum isotopes have been measured by collinear laser spectroscopy. From the obtained hyperfine-structure-coupling constants, moments of these nuclei have been determined. By comparing these moments with the theoretical ones calculated on the basis of Nilsson model, it has been found that there is significant disagreement between theoretical and experimental values of the quadrupole moment of 
La. It has already been predicted theoretically from the potential energy surfaces calculation using Woods-Saxon potential that the La nuclei around A=130 are largely triaxial. Because the triaxial deformation is not taken into consideration in the Nilsson model, the discrepancy could be attributed to the axially symmetric character of this model. A hyperfine structure anomaly found between 
La and 
La is also discussed.

Ion microbeam technology, in which the beam spot size and the irradiation position accuracy in the target are accurately controlled to 1 um level or it or less, has been advanced in the ion irradiation research facilities TIARA of JAEA Takasaki. Four microbeam systems of a light ion, a heavy ion, and a high energy heavy ion (collimating method and focusing method) have been produced, and the highly accurate beam control technology at micron level such as the local-area trace element analysis, the material micro fabrication, and the single ion hit technology, etc. has been established on these so far. The applied research to the biomedicine, the environmental science, the materials science, irradiation effects to the semiconductor, and the living cell has been progressed by cooperation with the researcher in the inside and outside of JAEA. This presentation reviews the development of microbeam forming techniques, the advanced techniques of microbeam analysis and the single ion hit, and the applied research using these microbeam techniques in TIARA.

The neutron diffraction method is known to be a nondestructive method which can measure the residual strain and stress in material with a few centimeter order depth. Furthermore, the microstructural factors, such as the microstrain, texture and dislocation density, can be evaluated by analyzing the diffraction pattern measured by neutron diffraction. In the presentation, I will show what we can obtain using neutron diffraction for materials engineering research and also show the expectation of RANS (RIKEN Accelerator-driven compact Neutron Source) in this research field.
