Electron correlation in time and space studied by Resonant InelasticX-ray Scattering - focused on strongly correlated electron systems-

成功地进行了以下三个方面的升级：(1)引入最新研制的二维像素探测器，实现了高能量分辨率。实现了10keV下70 meV的分辨率。(2)偏振分析RIXS方法的发展。成功地观察到了KCuF3的d-d激发。(3)多分析仪系统的开发。利用这些技术，我们成功地观察到了掺杂铜酸盐中动量相关的带内激发。

The following three upgrades have been succeeded: (1) high energy resolution by introducing newly developed two-dimensional pixel detector. The 70meV resolution at 10keV has been achieved. (2)Development of Polarization-analyzed RIXS method. The d-d excitation on KCuF3 has been observed in success. (3)Development of Multi-analyzer system. By using these techniques, the momentum dependent intra band excitation in doped cuprates has been observed successfully.
