The Super-Kamiokande Collaboration
- T. Futagami, Y. Fukuda, +110 authors R. Wilkes
- Physics
- 1999
A total of 614 upward through-going muons of minimum energy 1.6 GeV are observed by Super-Kamiokande during 537 detector live days. The measured muon flux is (1.74 ± 0.07(stat.) ± 0.02(sys.)) × 10… Expand

Evidence for oscillation of atmospheric neutrinos
- Y. Fukuda, T. Hayakawa, +118 authors K. K. Young
- Physics
- 1998
We present an analysis of atmospheric neutrino data from a 33.0thinspthinspktonthinspthinspyr (535-day) exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent deficit of… Expand
Tomographic imaging of P and S wave velocity structure beneath northeastern Japan
- D. Zhao, A. Hasegawa, S. Horiuchi
- Geology
- 10 December 1992
The seismic body wave tomography method has been improved and extended to adapt to a general velocity structure with a number of complexly shaped seismic velocity discontinuities (SVDs) and with… Expand
A theory of long period magnetic pulsations 1
- L. Chen, A. Hasegawa
- Physics
- 1 March 1974
A theory of long-period (Pc 3 to Pc 5) magnetic pulsations is presented based on the idea of a steady state oscillation of a resonant local field line that is excited by a monochromatic surface wave… Expand
Nonlinear pulse propagation in a monomode dielectric guide
- Y. Kodama, A. Hasegawa
- Physics
- 1 May 1987
We derive the nonlinear wave equation for an envelope of an electromagnetic wave in a monomode dielectric waveguide. Concrete examples are given for a single-mode optical fiber where the coefficients… Expand
Repeating earthquakes and interplate aseismic slip in the northeastern Japan subduction zone
- Toshihiro Igarashi, T. Matsuzawa, A. Hasegawa
- Geology
- 1 May 2003
[1] On the basis of a waveform similarity analysis, we detected 321 earthquake clusters with very similar (cross-correlation coefficient >0.95) waveforms on the plate boundary in the northeastern… Expand
Shear-wave polarization anisotropy and subduction-induced flow in the mantle wedge of northeastern Japan
- J. Nakajima, A. Hasegawa
- Geology
- 15 September 2004
Abstract Shear-wave polarization anisotropy in the central part of northeastern (NE) Japan was investigated. We analyzed S phases of 293 intermediate-depth earthquakes recorded at 77 stations and… Expand
The Super-Kamiokande detector
- S. Fukuda, Y. Fukuda, +174 authors H. Kobayashi
- Physics
- 1 April 2003
Super-Kamiokande is the world's largest water Cherenkov detector, with net mass 50,000 tons. During the period April, 1996 to July, 2001, Super-Kamiokande I collected 1678 live-days of data,… Expand
Japanese evaluated nuclear data library version 3 revision-3: JENDL-3.3
- K. Shibata, T. Kawano, +22 authors Hideki Takano
- Chemistry
- 25 November 2002
The revision work of JENDL-3 has been made by considering feedback information of various benchmark tests. The main revised quantities are the resonance parameters, capture and inelastic scattering… Expand
Three‐dimensional structure of Vp, Vs, and Vp/Vs beneath northeastern Japan: Implications for arc magmatism and fluids
- J. Nakajima, T. Matsuzawa, A. Hasegawa, D. Zhao
- Geology
- 10 October 2001
We estimated both P (V p ) and S wave velocity ( V s ) structures beneath northeastern Japan by applying a tomographic method to 169,712 P and 103,993 S wave arrival time data from 4338 local events.… Expand
