JOURNAL FREE ACCESSThe human race continue performing astrometry which provides positions and motions of stars shining with a night sky in order to find out a new natural law from ancient times. At the close of the 20th century, the space astrometry with a sufficient precision was performed for the first time without atmospheric turbulence. In the 21st century some plans of more accurate astrometry are advancing. In the text, I will show you the followings; the history of astrometry, the present and future status of the observation precision, examples of scientific objectives in the future astrometry such as clarification of the dynamical structure of the Milky Way Galaxy which is a self-gravitating system, introduction of some plans of future highly precise astrometry in the world, and finally JASMINE (Japan Astrometry Satellite Mission for INfrared Exploration) which is now developing in Japan.View full abstractDownload PDF (1359K) -

JOURNAL FREE ACCESSSolar neutrino observations utilizing tiny cross section of neutrinos have revealed the long-standing "solar neutrino problem." The problem was a breakthrough in measurement of neutrino properties and in new theories beyond the standard particle theory. It has contributed to an evolution of particle physics. The resolution of the problem has been obtained by solar neutrino experiments and the KamLAND reactor neutrino experiment. KamLAND has obtained a clear signature of oscillatory neutrino behavior and, as a result, it has determined a neutrino oscillation parameter related to neutrino mass very precisely. Now the accumulated knowledge on neutrino propagation opens new research area by using neutrinos as a prove of interior of the earth and the sun.View full abstractDownload PDF (1359K) -

JOURNAL FREE ACCESSAppearance of ferromagnetism in normally nonmagnetic materials in the size of nanometer scale has been theoretically predicted. This originates from the intrinsic change in the electronic structure due to the low dimensional character of nano-scale material. Despite of the theoretical prediction, few experimental studies have succeeded in verifying the appearance of ferromagnetism. In this study, we have demonstrated a clear evidence that the ferromagnetism appears in polyhedral Pd fine particles with a clean surface. Furthermore, the ferromagnetism of Pd fine particle appeared only on the (100) facet of the polyhedral particle.View full abstractDownload PDF (1190K) -

JOURNAL FREE ACCESSIn rare-earth compounds, electric quadrupoles of 4f electrons play important roles in determining their magnetic and electric properties. Recently, we have observed modulated quadrupolar structures below TQ=0.4K in the rare-earth compound PrPb3 by means of neutron diffraction technique. In these ordered phases, interaction between quadrupoles is the RKKY-like indirect one, therefore, electric quadrupole, such as magnetic dipole moment, can play a main part which bring about variable properties.View full abstractDownload PDF (1153K) -

JOURNAL FREE ACCESSThe traditional interpretation of Hund's rule due to exchange energy is not correct, which has already been verified for low-lying excited states of helium isoelectronic systems and light molecules. The stability of the highest spin multiplicity state is in fact ascribed to a decrease in the predominant electron-nucleus interaction energy of the system, which is realized at the cost of increasing the electron-electron interaction energy as well as the kinetic energy. The present article states that the same conclusion applies to the ground state of carbon, nitrogen, and oxygen atoms.View full abstractDownload PDF (1085K) -

JOURNAL FREE ACCESSAfter the conclusion that the quark spin is responsible only 20-30% for the nucleon spin, it has been expected that the gluon spin will possibly cancel the lack of the spin. Then, the subject to measure the contribution of gluon spin to the nucleon spin has been an urgent issue. This subject has been proposed at several laboratories like CERN, DESY, BNL etc., and is presently intensively being progressed. COMPASS has started the measurement of the gluon polarization ⊿G/G from 2002. Here, we will show the progress of the COMPASS project and very preliminary results on the measurement of gluon polarization, longitudinally polarized DIS asymmetry, and Collins asymmetry to the transversely polarized deuteron.View full abstractDownload PDF (919K) -
