Times Cited Count：3 Percentile：17.87(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 LaSrCuO and oxygen-doped LaCuO. 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).

Times Cited Count：66 Percentile：88.61(Materials Science, Multidisciplinary)We have performed a temperature-dependent angle-integrated photoemission study of LaSrCuO covering from lightly doped to heavily overdoped regions and oxygen -doped LaCuO. The superconducting gap energy 
was found to remain small for decreasing hole concentration while the pseudogap energy 
and temperature 
increase. The different behaviors of the superconducting gap and the pseudogap can be explained if the superconducting gap opens only on the Fermi arc around the nodal (0,0)-
direction while the pseudogap opens around 
. The results suggest that the pseudogap and the superconducting gap have different microscopic origins.

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.

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.
