Research Interests
Low and intermediate energy electron-atom and electron-molecule
collisions, ionization and fragmentation of few-electron systems,
photoionization of atoms and molecules, analyticity and resonance
phenomena.
Dr. Rescigno's research activities are focused on the theoretical
investigation of electron and photon collisions with atoms
and molecules. The tools of modern computation quantum chemistry
are being combined with variational scattering theory methods
to provide a theoretical attack on a wide range of problems
in 'Electron-Driven Chemistry'. The complex Kohn variational
method has provided the framework for studying electron- and
photon-collisions with a number of polyatomic targets. Of
particular current interest in his group are resonant electron
collisions with polyatomic molecules and the mechanisms whereby
electronic energy is transferred into nuclear degrees of freedom.
Dr. Rescigno has had a long-standing interest in developing
methods for obtaining scattering cross sections from calculations
carried out in Hilbert space. He has concentrated on the adaptation
of novel, non-traditional approaches to problems in collision
physics. This has included techniques of complex analysis
as well as Hilbert space methods normally associated with
problems in bound-state electronic structure. Recent research
efforts in his group using exterior complex scaling and massively
parallel computation have led to the first solution of the
long-standing problem of a complete quantum description of
collisional breakup of a quantum three-body system.
