Times Cited Count:1 Percentile:4.7(Physics, Applied)An improvement of laser-focused peak intensity has been achieved in a JAERI 100 TW Ti:sapphire chirped-pulse amplifier chain with a feedback-controlled adaptive optics system. Measurements of optical parameters of the laser pulse and an experimental tunneling ionization ratio of a rare gas atom with laser energy scaling have practically confirmed an ultrarelativistic intensity of over 10 W/cm operating at a 10 Hz repetition rate.

Resonant inelastic X-ray scattering (RIXS) measurements at the Fe edge have been performed for recently discovered iron-pnictide superconductors. The aim of the present study is to analyze theoretically the results of the experiments. Specifically, we use a 16-band d-p model, where the Fe3d and As4p orbitals are taken into account, and the electron correlation effects are taken into account within the random-phase approximation (RPA).
