Section A, Research, 1954-1986: Notebooks, research papers and reports. The notebooks, 1957-1986, consist of rough notes on research carried out at the Atomic Energy Research Establishment Harwell and at the University of Sussex. There are also three notebooks of experimental results kept while at Atomic Energy of Canada Limited, Chalk River Nuclear Laboratories, Ontario in 1968. The research papers, 1954-1985 were categorised by Thompson as either theoretical or experimental. There are also research papers which were not placed by Thompson in either category.

Lists of publications and reports and a mailing list can be found together with off-prints of Thompson' scientific papers.
