Abstract

Ion yields of C<sup>+n</sup>(n<6) from methane, ethane, butane and octane are measured from 10<sup>13</sup>W/cm<sup>2</sup>to 10<sup>19</sup>W/cm<sup>2</sup>, with photoelectron spectra up to 0.5 MeV. As one reaches 10<sup>17</sup>W/cm<sup>2</sup>the molecular response becomes atomic-like.
