Small rare-gas clusters in soft x-ray pulses.

چکیده
We develop a microscopic model for the interaction of small rare-gas clusters with soft x-ray radiation from a free electron laser. It is shown that, while the overall charging of the clusters is rather low, unexpectedly high atomic charge states can arise due to charge imbalances inside the cluster. These findings are explained by an increased absorption via inverse bremsstrahlung due to high intermediate charge states and by a nonhomogenous charge distribution inside the cluster.

We develop a microscopic model for the interaction of small rare gas clusters with soft X-ray radiation. It is shown that, while the overall charging of the clusters is rather low, unexpectedly high atomic charge states can arise due to charge imbalances inside the cluster. The mechanism does not require unusually high absorption rates, and the heating can be described by standard inverse brems...
متن کاملIonization of clusters in strong x-ray laser pulses.
The effect of intense x-ray laser interaction on argon clusters is studied theoretically with a mixed quantum/classical approach. In comparison to a single atom we find that ionization of the cluster is suppressed, which is in striking contrast to the observed behavior of rare-gas clusters in intense optical laser pulses. We have identified two effects responsible for this phenomenon: A high sp...
متن کاملOptimal generation of spatially coherent soft X-ray isolated attosecond pulses in a gas-filled waveguide using two-color synthesized laser pulses
We numerically demonstrate the generation of intense, low-divergence soft X-ray isolated attosecond pulses in a gas-filled hollow waveguide using synthesized few-cycle two-color laser waveforms. The waveform is a superposition of a fundamental and its second harmonic optimized such that highest harmonic yields are emitted from each atom. We then optimize the gas pressure and the length and radi...
متن کاملRadiographic Presentations of Intussusception in Plain Abdominal X-Ray
Intussusception is the most common cause of intestinal obstraction in children aged 3 months to 6 years. Complete understanding of its clinical and radiographic manifestations can play a major role in the early diagnosis and treatment and prevents its complications. In this study plain abdominal X-rays of 51 patients with intussusception were evaluated. Suggestive radiographic signs of the dise...
متن کاملSmall rare gas clusters in XUV laser pulses
Semi-classical molecular dynamics simulations of small rare gas clusters in short laser pulses of 100nm wavelength were performed. For comparison, the cluster response to 800nm laser pulses was investigated as well. The inner ionization dynamics of the multi-electron atoms inside the cluster was treated explicitly. The simulation results underpin that at XUV wavelengths collisions play an impor...
