Photoemission dynamics in the molecular frame

Abstract

Photoemission dynamics, based on the molecular frame photoelectron angular distribution, is reported. In the fast decay channel leading to Ne+ + Ne2+ of Ne2 dimer, the molecular frame photoelectron measurements have been realized, and the core-hole localization observed. However, in the slow decay channel leading to Ne+ + Ne+, such measurements have not been applicable as expected. The molecular frame photoemission study has been extended to a non-axially symmetric H2O molecule, and its experimental result has been well explained by a simple scattering model which is widely used in surface science.
