Times Cited Count：6 Percentile：27.03(Materials Science, Multidisciplinary)We have studied the Mott transition of BaCoS by pressure and Ni substitution using 
SR, and examined the appearance of the quantum phase transition. The results show that both quantum phase transitions are first-order transitions at zero temperature.

Times Cited Count：4 Percentile：36.66(Physics, Multidisciplinary)A development has been achieved in the identification method of the charges 1 to 5 of nuclides from the decay of double hypernuclei to be uniquely recognized by their nuclear species. The method is basically the measurement of track volume by the widths, depths, and angles of tracks of exposed nuclei of 
H, 
He, 
Li, 
Be, and 
B in nuclear emulsion at Riken Projectile-fragment Separator of RIKEN Radioactive Isotope Beam Factory. After their calibration by 
particles, we obtained a quadric function to present a unified recognition of tracks with volume ratios of five nuclei to the particles. The function in the emulsion has been applied to a candidate event of a 
hypernucleus for identification of the production and decay processes. We succeeded in recognizing a daughter nuclear fragment of a single-
hypernucleus as 
He with a likelihood ratio of 0.9; the process was then uniquely identified as 
+ 
N 
Be +

Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed since 1975, based on "Safety regulations for the Tokai Reprocessing Plant, Chapter VI - Environmental Monitoring". This annual report presents the results of the environmetal monitoring and the dose estimation to the hypothetical inhabitants due to the annual discharged radioactivity from the plant during 1988. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data, annual discharges from the plant and details of dose estimation.
