John Hays "Jack" Moore, Jr., 68, of State College, Pennsylvania died suddenly Sunday, May 2, 2010. Born Nov. 6, 1941, in Pittsburgh, Jack w as a son of the late John Hays and Mary Welfer Moore. On Aug. 10, 1963, he married Judy Williams, who survives him. A native of Pittsburgh, PA, Jack was a 1959 graduate of Clairton High School. He completed his undergraduate studies (in mathematics) at the Carnegie Mellon University. He then obtained his doctorate in physical chemistry at The Johns Hopkins University in 1967, working under the direction of Dean Robinson. Jack continued at Johns Hopkins as a postdoctoral fellow in the laboratory of John Doering, before taking, in 1969, a faculty position in the Department of Chemistry (now Department of Chemistry and Biochemistry) at the University of Maryland.

At Maryland, Jack quickly established an internationally recognized experimental program in the use of ion-impact spectroscopy to study optically-forbidden transitions in small organic molecules. Jack extended this work later to the study of stable and metastable negative-ion states of a wide variety of organic and metallo-organic molecules.

During a visiting fellowship at the Joint Institute for Laboratory Astrophysics in Boulder, CO, working with Ed Beatty, Jack was introduced to coincidence detection of charged particles. Returning to Maryland, and in collaboration with Michael Coplan of the Institute for Physical Science and Technology of the University of Maryland, Jack subsequently extended his work on electron-impact ionization spectroscopy to permit the detection, in coincidence, of the scattered and ejected electrons. These (e,2e) experiments probed directly the square of the momentum-space wavefunctions for individual atomic and molecular orbitals.

In many of Moore's investigations of electron-molecular scattering, interpretation of the experiments was greatly aided by a close and long-standing collaboration with John Tossell, also of the Department of Chemistry and Biochemistry (now at the Virginia campus of the George Washington University), a quantum chemist. In his most recent research achievement, Jack, along with Coplan, John Doering (Jack's postdoctoral advisor) and John Cooper (formerly of NIST), initiated the triple-coincidence study (e,3e) of the interaction between direct and indirect (Auger) ionization in simple systems.

Complementing his multiple contributions to basic research, Jack was the lead author, along with his colleagues Michael Coplan, Christopher Davis, and Sandra Greer, of the extremely successful book "Building Scientific Apparatus," now in its 4th edition. He was also a co-editor, along with Nicholas Spencer (Federal Technical University, Zurich, Switzerland) of the Encyclopedia of Chemical Physics and Physical Chemistry. In addition, Jack was instrumental in the evolution of the undergraduate curriculum in Chemistry at the University of Maryland, first in the development, along with Thomas O'Haver, of the Chemical Measurements Laboratory, and then, in the early 2000's, in the redesign of the introductory chemistry sequence. Finally, Jack was for many years the associate chair of the Chemical Physics graduate program at the University of Maryland, a program of consistently high quality and one of the very few in this discipline nationwide.

In addition to his varied contributions to science and education, Jack was an accomplished equestrian, cellist, sportsman, and pilot. Along with his wife, he is survived by two children: John Hays Moore III of Alexandria, Va. (subsequently deceased) and Victoria Inez Moore of Rochester, N.Y., and two brothers: James Welfer Moore and his wife, Arvella Moore, of Sharpsburg, Ga., and Paul Andrew Moore and his wife, Elaine Scott Moore, of Pittsburgh.
