Multielectron, nonsequential ionization has been measured up to Xe<sup>11+</sup>. The data shows rescattering collisions at 10<sup>16</sup>W/cm<sup>2</sup> to 10<sup>17</sup>W/cm<sup>2</sup> and across electron shells. A rescattering deflection parameter predicts the change from the strong to ultrastrong field.
