Intramolecular Dynamics due to Electron Transitions: From Photoelectron Spectroscopy to Femtochemistry

January 1, 1999

Author(s)

John William Gadzuk

A personal recollection of the coming-to-an-understanding of select spectroscopic and then chemical physics problems associated with atomic motion triggered by electronic transitions is given. The story starts with the initial stimulation provided by Dick

Introduction to Time and Frequency Metrology

Investigation of Nonlinear Material Behavior Using Simultaneous Measurements of Volume Recovery and Physical Aging

January 1, 1999

Author(s)

Carl R. Schultesiz, G B. McKenna

At temperatures below the glass transition, amorphous polymers evolve slowly toward thermodynamic equilibrium. Some experiments have suggested that different material properties equilibrate at different rates, but such comparisons are typically made using

Investigative Tools: Experimental Methods and Probes

January 1, 1999

Author(s)

J Murday, Robert Celotta, D Pui, P West

Ion-Molecule Reactions and Ion Kinetics in DC Townsend Discharges in Dielectric Gases

January 1, 1999

Author(s)

MVVS. Rao, James K. Olthoff

The transport of positive and negative ions plays an important role in the initiation and behavior of discharges in gaseous dielectrics. In many cases, the identities, intensities, and kinetic energies of ions are determined by ion-molecule collisions

Dale E. Newbury, David S. Bright

Digitally-recorded electron-excited x-ray maps are processed in a variety of ways to improve the visibility of features. Scaling of the recorded signal to match the 8-bit gray scale intensity range of a typical computer display system is almost always
