The techniques of electron-electron and electron-ion covariance mapping have been used to confirm that a laser of modest rise time ({similar to}1 ps) and focused intensity ({similar to}10{sup 15} W/cm{sup 2}) will doubly ionize {ital H}{sub 2} molecules in a sequential manner. This stepwise behavior manifests itself in structureless features on the electron-electron maps. However, the technique can be employed to search for correlated emission of two or more electrons in more complex systems. Electron-ion maps, on the other hand, can apportion the electrons in a typical photoelectron spectrum to the parent ions and to fragment ions of all energies.
