  The interaction of high intensity laser radiation with mass-limited target
exhibits significant enhancement of the ion acceleration when the target is
surrounded by an underdense plasma corona, as seen in numerical simulations.
The self-generated quasistatic magnetic field squeezes the corona causing the
intensification of a subsequent Coulomb explosion of the target. The electric
field intensification at the target edges and plasma resonance effects result
in the generation of characteristic density holes and further contributes to
the ion acceleration.The interaction of high intensity laser radiation with
