heal.abstract	We investigate both theoretically and experimentally the momentum distribution of multiply charged ions ionized by an intense multicycle laser field with a maximum intensity of ̃(50-70) 0.3em PW/. Ions with different charge states are produced during a single laser shot due to a spatial variation of the laser intensity within the beam focus. The measurements show approximately a simple linear relation between the width of the momentum distributions and the ionization potential of the ions. Such a power law scaling appears to be universal for various rare gas atoms used (He, Ne, Ar). We analyze this ionization dynamics using a quasiclassical tunneling theory for a single active electron model assuming that the interaction between electrons is negligible in such a strong field limit. We show that for the relatively long pulses used in the present work (̃ 200 0.3em fs or ̃ 80 0.3em cycles) the effect of the laser envelope plays an important role in the ionization process. © 2007 The American Physical Society.	en
