Research Statement | | King Walters came to Rice after a number of highly productive
years in industrial research. Here, he initiated the development of
atomic, molecular and surface physics research programs. His research
focuses on manifestations of electron spin and has ranged from
development of polarized targets for nuclear physics experiments
through gas-phase collisions in a variety of environments to
fundamental physics of surfaces.
In close collaboration with Barry
Dunning, Walters has studied the spin-dependence of numerous
gas-phase reactions of spin-polarized helium atoms, has produced one
of the most intense sources of spin-polarized electrons in the world
and has developed a range of spin-sensitive surface probes that are
now unlocking the secrets of magnetic behavior of surfaces and
dynamics of particle-surface interactions.
The newest of these surface probes entails measurement of the spin
orientation of electrons ejected from surfaces by spin-polarized,
helium ions. This complex technique requires the unique combination
of basic atomic physics, surface science and laser expertise existing
within the Rice Quantum Institute.
