Times Cited Count:3 Percentile:17.80(Physics, Applied)In the high- research, relationship between the pseudogap and the superconducting gap has been an important issue. We have performed a detailed temperature-dependent angle-integrated photoemission study of lightly-doped to heavily-overdoped La
Sr
CuO
and oxygen-doped La
CuO
. We found that, while the magnitude of the pseudogap increased with decreasing doping, that of the superconducting gap did not increase. This behavior can be explained if the superconducting gap opens only on the Fermi arc around the node (0,0)-(
,
) whereas the pseudogap opens primarily around (
,0).

To clarify the damage behavior under ion irradiation in quartz glass, Age-Momentum Correlation measurement that is a coincidence measurement of positron annihilation lifetime and annihilation gamma ray Doppler broadening was performed under 2 MeV proton irradiation. From the change in momentum distribution of electrons involved in positron annihilation in voids of the quartz glass, flux dependence of damage behavior could be detected.

We compiled the magnetotelluric (MT) and geomagnetic transfer function (GDS) data which were acquired by Uchida (2004), Umeda et al. (2008), Asamori et al. (2011), Uyeshima (private comm.) and Ogawa (private comm). The 118 observation sites locate in the study area. Both MT and GDS frequency response was used to model three-dimensional resistivity distribution of the southern Tohoku district, NE Japan. The resultant resistivity model reveals no conductor beneath the onshore forearc in Fukushima prefecture. The model rather shows resistor there with over several-thousand ohm-m, which corresponds to the Abukuma batholiths. Thus, our model indicates that the area only around Iwaki-city is peculiar forearc, where fluid migrates upward from deep crust.

An electric quadrupole moment ( moment) is sensitive to collective aspects of nuclear structure. In the
-moment measurement for unstable nuclei, we employ the
-detected nuclear-quadrupole resonance method. In this method, we need to supply
resonance frequencies, where
denotes the nuclear spin. We have developed a new RF-application system to induced all of the
transitions. The application of the
frequencies may be pursued in two different ways; the sequential RF pulse method and the mixed-wave RF pulse method. We confirmed the reversal of polarization for the both methods, from measurements of
-ray asymmetry change for polarized
B. Using this system, the
moments of
Al have been measured to be
mb and
mb by the sequential RF pulse method.

Terrace to terrace (TT) method is mainly used for estimating uplift rate on mountain areas of Japan on 10-year time scale. However, this method cannot be applied to the area with poor distribution of fluvial terraces. In such area, the method based on the emergence ages of the fluvial landform, e.g., an abandoned river valley around a cutoff spur, and the relative elevation between old and present reiver bed is expected instead of TT method. This method calculates the river-incision rate by dividing the relative elevation by the emergence age. The river-incision rate is equal to the uplift rate if the river is at equilibrium (graded stream). We are investigating the fluvial landform in the Oi River basin for verifying this method. In this presentation, we will present the incision and uplift rate estimated by feldspar OSL dating results.
