The research under the direction of Dr. Coppens will make                       extensive use of the synchrotron radiation facilities at the                    National Synchrotron Light Source and at the Cornell High                       Energy Synchrotron Source.  A major effort will focus on the                    structural analysis of modulated solids, in which the                           three-dimensional symmetry is modified by superposition of                      incommensurate modulation waves.  Such modulations can strongly                 affect physical properties such as electrical conductivity.  In                 addition Dr. Coppens will develop further the experimental                      capability of his laboratory at SUNY-Buffalo to carry out low                   temperature measurements.  This capability will complement the                  work at the synchrotron facilities by permitting preliminary                    measurements to be carried out in a more systematic manner.                                                                                                     This research activity on electron densities and phase                          transitions in molecular crystals is expected to provide new                    fundamental insights in several areas.  In particular, the                      understanding of electrical conductivity and superconductivity                  is still not complete.  These studies could impact the search                   for new materials for electronic devices or for high                            temperature superconductors.
