A new design for generation of tunable gamma-ray with a fixed energy electron beam (2009)
Ohgaki, Hideaki, Kii, T., Toyokawa, H.
A tunable quasi-monochromatic gamma-ray beam is indispensable not only for radiation measurements, but also for precise measurements of nuclear data. A design for generation of tunable...
The Infrared Astronomical Mission AKARI (2007)
Murakami, H., Baba, H., Barthel, P., Clements, D. L., Cohen, M., Doi, Y., ...
AKARI, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year. AKARI has a 68.5 cm cooled telescope, together...
Shima, T., Naito, S., Nagai, Y., Baba, T., Tamura, K., Takahashi, T., ...
We have performed for the first time the simultaneous measurement of the two-body and three-body photodisintegration cross-sections of 4He in the energy range from 21.8 to 29.8 MeV using...
ASTRO-F - Super IRAS - The All Sky Infra-Red Survey (2002)
Pearson, Chris, Shibai, H., Matsumoto, T., Murakami, H., Nakagawa, T., Kawada, M., ...
We review the next generation Japanese infrared space mission, ASTRO-F. ASTRO-F will be the first survey of the entire sky at infrared wavelengths since the IRAS mission almost 20 years ago. ASTRO-F...

Non-resonant direct p- and d-wave neutron capture by 12C (1998)
Kikuchi, T., Nagai, Y., Suzuki, T. S., Shima, T., Kii, T., Igashira, M., ...
Discrete gamma-rays from the neutron capture state of 13C to its low-lying bound states have been measured using pulsed neutrons at En = 550 keV. The partial capture cross sections have been...
Fluctuations in the diffuse X-ray background observed with Ginga (1997)
Butcher, J. A., Stewart, G. C., Warwick, R. S., Fabian, A. C., Carrera, F. J., Barcons, X., ...
We present Ginga measurements of the spatial fluctuations in the diffuse X-ray background. When combined with earlier results, the new data constrain the extragalactic log N - log S relation in the...
Urry, C. Megan, Treves, A., Maraschi, L., Marshall, H., Kii, T., Madejski, G., ...
In May 1994 the BL Lac object PKS 2155-304 was observed continuously for ~10 d with IUE and EUVE and for 2 d with ASCA, as well as with ROSAT and with ground- based radio, IR, and optical telescopes....
The ASCA X-ray spectrum of the powerful radio galaxy 3C109 (1997)
Allen, S. W., Fabian, A. C., Idesawa, E., Inoue, H., Kii, T., Otani, C.
We report the results from an ASCA X-ray observation of the powerful Broad Line Radio Galaxy, 3C109. The ASCA spectra confirm our earlier ROSAT detection of intrinsic X-ray absorption associated with...
ASCA Observations of the Composite Warm Absorber in NGC 3516 (1996)
Kriss, G. A., Krolik, J. H., Otani, C., Espey, B. R., Turner, T. J., Kii, T., ...
We obtained X-ray spectra of the Seyfert 1 galaxy NGC~3516 in March 1995 using ASCA. Simultaneous far-UV observations were obtained with HUT on the Astro-2 shuttle mission. The ASCA spectrum shows a...
The variable OVIII Warm Absorber in MCG-6-30-15 (1995)
Otani, C., Kii, T., Reynolds, C. S., Fabian, A. C., Iwasawa, K., Hayashida, K., ...
We present the results of a 4 day ASCA observation of the Seyfert galaxy MCG-6-30-15, focussing on the nature of the X-ray absorption by the warm absorber, characterizd by the K-edges of the...
