Abstract

Photodouble Ionization (PDI) is of fundamental interest because it results in an ion and two escaping electrons which are subject to long-range Coulomb forces. The most sensitive and direct way of studying this 3-body Coulomb problem is to use synchrotron radiation and measure the angular distributions (or Triple Differential Cross Sections, TDCS) of the two outgoing electrons using coincidence techniques. PDI in helium is the archetypal system for these studies because a bare nucleus is left behind and no process other than direct double ionisation can occur.
