Times Cited Count：34 Percentile：83.98(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：7 Percentile：46.50(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：34 Percentile：88.41(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.

Times Cited Count：16 Percentile：72.08(Chemistry, Analytical)We present real time Vanadate (V
) uptake imaging in a cowpea plant by Positron Emitting Tracer Imaging System (PETIS). Vanadium-48 was produced by bombarding a Sc foil target with 50 MeV -particles at Takasaki Ion accelerators for Advanced Radiation Application (TIARA) AVF cyclotron. Then 
V was added to the culture solution to investigate the V distribution in a cowpea plant. The real time uptake of the V was monitored by PETIS. We measured the distribution of V in a whole plant after 3, 6 and 20 hours of V treatment by Bio-imaging Analyzer System (BAS). After the 20 hour treatment, vanadate was detected at the up-ground part of the plant. To know the effect of V uptake on plant activity, F-labeled water uptake was analyzed by PETIS. When a cowpea plant was treated with V for 20 hours before F-labeled water uptake experiment, the total amount of F-labeled water absorption was drastically desreased. Results suggest the inhibition of water uptake was mainly caused by the vanadate already moved to the up-ground part of the plant.
