Abstract

The Coulomb explosion of $H_{2} O$ in laser pulses of 50 fs and intensity of $3 \times 10^{16} {W / c m}^{2}$ has been investigated using an ion momentum-imaging technique to determine the shape of the exploding molecule. The molecule is found to straighten substantially during the ionization process with the bend distribution at a maximum between $130 °$ and $180 ° .$
