Times Cited Count：33 Percentile：84.97(Astronomy & Astrophysics)The excitation function of the 
Li(,n)B reaction was measured while identifying the final state event by event in the region of E
= 0.7 - 2.6 MeV using a highly efficient detector system and a low-energy Li beam. The results are much improved both in statistics and precisions, and show smaller cross sections than those of previous measurements by a factor of more than 2 in the low-energy region of E
1.5 MeV. A resonance-like structure is found at around E = 0.85 MeV.

Times Cited Count：46 Percentile：90.03(Physics, Nuclear)The scattering of the radioactive, weakly bound, halo nucleus Be from Bi has been studied at 40 MeV. The measurement performed with a low-intensity and a large-emittance secondary beam could be made using an extremely compact, large solid angle (
2
sr) detecting set-up, based on 8 highly segmented Si telescopes. The 
Be scattering angular distributions, as well as their relative reaction cross-sections, resulted to be rather similar. This may suggest that at Coulomb barrier energies the halo structure and the small weakly binding energy of the Be projectile have no big influence on the reaction dynamics.

Times Cited Count：7 Percentile：47.51(Instruments & Instrumentation)Thanks to the nature of inverse transfer-reactions, low-energy radioactive nuclear beams in light neutron-rich region were produced. The mass-separation and velocity-separation of the JAERI recoil mass-separator help to form high purity beams. The beams of Li, 
B, and 
N-RNBs are utilized to the experiments, so far, with those beam intensities and purities of 1.4

Times Cited Count：33 Percentile：89.07(Instruments & Instrumentation)A new type of three dimensional tracking and proportional gas counter has been developed. Adopting a gating-grid system, performance of the detector becomes stable under the injection rate of charged particles less than 410 pps. It is a useful detection system for astrophysical experiments using radioactive nuclear beams, since the efficiency is so high as 100 %.

Authors developed a radiotracer method for diffusion studies in solids. The experimental test was performed by the measurement of the diffusion coefficients of Li in a sample of the compound 
LiAl using an -emitting radiotracer of Li(T
= 0.84 s). It was found that the time-dependent yields of the alpha particles from the diffusing 8Li that was initially implanted in the sample could be used as a measure of the diffusivity of the tracer in a nondestructive way. The method was applied to measure the self-diffusion coefficients of Li in LiGa, and for investigating how the Li diffusion in the Li ionic conductors is affected by the concentration of atomic defects.

To select and to presume the parameters adaptable to biosphere assessment of geological disposal at an actual environment, the procedure of updating a database using the domestic biosphere data was developed and was tried to a part of element-specific parameters. As a result, we were able to set the reliable biosphere parameters, by arranging important background information to secure the reliability of the parameter.
