Effect of Rabi dynamics in resonant x-ray scattering of intense attosecond pulses

Abstract

We theoretically study the effects of Rabi oscillations on resonant x-ray scattering in Ne$^+$ using intense attosecond and few-femtosecond pulses. The total photon yield strongly depends on the pulse area and has an upper bound at high intensities. Resonant scattering yields with attosecond pulses can be an order of magnitude higher than those far from resonances. Interference between resonant fluorescence and elastic scattering channels depends on the pulse area and initial state. Our results suggest that resonant x-ray scattering can be exploited for high-resolution, site-specific imaging.
