(U) MOLECULAR INTERACTIONS AND PROPERTIES WITH MANY-BODY METHODS

ABSTRACT (Continue on reverse if necessary and identify by block number) During the course of this research, CC/MBPT theories have been established as being among the 'most accurate available, and very efficient and generally applicable computer codes have been developed to perform CC/MBPT calculations. These methods have been employed for the first time in large scale ab initio calculations of potential energy surfaces. Two of the papers produced in this research have been identified by authorities as being among the most influential papers in the 50-year history of computational quantum chemistry, and four have been identified by Current Contents as qualifying as science citation classics. \
