Final state effects and correlation in atomic and molecular systems

PDF Version Also Available for Download.

Description

This is the final report of a three-year Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project`s goals were to experimentally examine phenomena caused by final state interactions of the photo-excited electron with the remaining ionic system. This includes multiple ionization by a single photon, which cannot be described solely within a one-electron framework, but requires explicit incorporation of correlation effects between the second electron and the primary electron. Having only two electrons, helium is one of the simplest systems which exhibits electron correlation and thus is an ideal choice for testing electron correlation ... continued below

Description

This is the final report of a three-year Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project`s goals were to experimentally examine phenomena caused by final state interactions of the photo-excited electron with the remaining ionic system. This includes multiple ionization by a single photon, which cannot be described solely within a one-electron framework, but requires explicit incorporation of correlation effects between the second electron and the primary electron. Having only two electrons, helium is one of the simplest systems which exhibits electron correlation and thus is an ideal choice for testing electron correlation models in atoms. The authors measured the double to single ionization ratio in helium and the multiple ionization ratio in several other rare gases to test the recent theories. They found an unexpected ionization channel caused by Compton scattering.
