Donald Frederick Gallaher used the Chilton Atlas in the period 1968-1969 for computations related to proton-hydrogen scattering in the Sturmian representation.
Donald Gallaher was a graduate of The University of British Columbia and the University of Toronto. He was awarded a Ph D at the University of Washington in the area of theoretical heavy particle atomic collisions in 1967.
He then became a Post-doctoral Research Fellow in the Department of Applied Mathematics and Theoretical Physics at the Queen's University of Belfast (QUB), becoming an Assistant Professor in July 1969.
The title of his PhD dissertation was Coupled State Calculations of Proton-Hydrogen Scattering in the Sturmian Representation and the programs developed on Atlas related to that work.
Papers published while at QUB included:
He continued working in this area after moving back to Canada and joining the University of Western Ontario in 1970.
