【 摘 要 】

We present a theoretical study of several kinds of interferences resulting from laser assisted x-ray photoionization of diatomic molecules. Double-slit-like interferences and confinement-like effects are studied within an analytical model, showing a qualitative agreement with ab-initio calculations. In the case of laser assisted photoionization, in the framework of a sudden approximation model, we analyze different pulse configurations that could lead to steer electron motion.
