Construction and finite generation of the strict closure of rings
Ryotaro Isobe
The construction of Arf rings and strictly closed rings has been studied widely; however, there has been no clear description of the structure of the strict closure R^* when the in…
A kinematic study of the disc-outflow system around a high-mass protostar G59.783+0.065 probed by methanol and water masers
M. Nakamura, K. Motogi, H. Nakamura +2
Class II CH3OH masers are used as a convenient tracer of disc-like structures in high-mass star formation. However, more than half of them show a complex distribution in Very Long…
Delivery of gas onto the circumplanetary disk of giant planets: Planetary-mass dependence of the source region of accreting gas and mass accretion rate
Natsuho Maeda, Keiji Ohtsuki, Takayuki Tanigawa +2
Gas accretion onto the circumplanetary disks and the source region of accreting gas are important to reveal dust accretion that leads to satellite formation around giant planets. W…
A global system of furrows on Ganymede indicative of their creation in a single impact event
Naoyuki Hirata, Ryo Suetsugu, Keiji Ohtsuki
Furrows are a concentric system of tectonic troughs, and are the oldest recognizable surface feature on Ganymede. We analyzed the distribution of furrows utilizing Voyager and Gali…
Synchronized excitation of magnetization dynamics via spin waves in Bi-YIG thin film by slot line waveguide
Tetsunori Koda, Sho Muroga, Yasushi Endo
We have studied magnetization dynamics of a single Bi-YIG thin film by means of the high frequency power response induced by a slot line waveguide. Multiple absorption peaks that c…
Magnetic monopoles in multi-vector boson theories
Koichiro Kobayashi, Nahomi Kan, Kiyoshi Shiraishi
A classical solution for a magnetic monopole is found in a specific multi-vector boson theory. We consider the model whose gauge group is broken by sigma-model fiel…
First application of superconducting transition-edge-sensor microcalorimeters to hadronic-atom x-ray spectroscopy
S. Okada, D. A. Bennett, C. Curceanu +35
High-resolution pionic-atom x-ray spectroscopy was performed with an x-ray spectrometer based on a 240-pixel array of superconducting transition-edge-sensor (TES) microcalorimeters…
Formation spectra of charmed meson--nucleus systems using an antiproton beam
J. Yamagata-Sekihara, C. Garcia-Recio, J. Nieves +2
We investigate the structure and formation of charmed meson--nucleus systems, with the aim of understanding the charmed meson--nucleon interactions and the properties of the charme…
Compositeness of baryonic resonances: Applications to the Delta(1232), N(1535), and N(1650) resonances
Takayasu Sekihara, Takashi Arai, Junko Yamagata-Sekihara +1
We present a formulation of the compositeness for baryonic resonances in order to discuss the meson-baryon molecular structure inside the resonances. For this purpose, we derive a…
Compositeness of the Delta(1232) resonance in pi N scattering
Takayasu Sekihara, Takashi Arai, Junko Yamagata-Sekihara +1
We evaluate the compositeness of the resonance so as to clarify the internal structure of in terms of the component. Here the compositeness is defined…
Status of the Bio-Nano electron cyclotron resonance ion source at Toyo University
T. Uchida, H. Minezaki, S. Ishihara +8
In the paper, the material science experiments, carried out recently using the Bio-Nano electron cyclotron resonance ion source (ECRIS) at Toyo University, are reported. We have in…
Synthesis of endohedral iron-fullerenes by ion implantation
H. Minezaki, S. Ishihara, T. Uchida +7
In this paper, we discuss the results of our study of the synthesis of endohedral iron-fullerenes. A low energy Fe+ ion beam was irradiated to C60 thin film by using a deceleration…
Fullerene-rare gas mixed plasmas in an electron cyclotron resonance ion source
T. Asaji, T. Ohba, T. Uchida +8
A synthesis technology of endohedral fullerenes such as Fe@C60 has developed with an electron cyclotron resonance (ECR) ion source. The production of N@C60 was reported. However, t…
Moment maps and Isoparametric hypersurfaces in spheres --- Hermitian cases
Shinobu Fujii, Hiroshi Tamaru
We are studying a relationship between isoparametric hypersurfaces in spheres with four distinct principal curvatures and the moment maps of certain Hamiltonian actions. In this pa…
Phase Fluctuation of Fermion Determinant in Lattice QCD at Finite Density
Y. Sasai, A. Nakamura, T. Takaishi
Once the quark chemical potential is introduced in finite density QCD, the fermion determinant appeared in the path integral measure becomes complex. In order to investigate th…
