| Additional Information: | © 1946 American Institute of Physics. Received July 22, 1946. Contribution No. 1020 from Gates and Crellin Laboratories. The preparation of the electron diffraction sets of punched cards involved the help of many people at various times in the period June 1940 to March 1941. We wish to acknowledge the various contributions to various phases of the work by Mr. H. Feldman, Dr. and Mrs. Paul Giguere, Mr. W. J. Howell, Jr., Dr. H. A. Levy, Dr. R. E. Rundle, Dr. M. T. Rogers, Dr. W. Shand, Jr., Dr. R. A. Spurr, Dr. S. M. Swingle, Dr. A. L. Wahrhaftig, Dr. J. Waser, Dr. S. Weinbaum, and Dr. W. West. We are also greatly indebted to the International Business Machines Corporation, which made available the machines for this work, and to the Committee on Scientific Aids to Learning, which made the California Institute of Technology a grant for the preparation of sets of punched cards and for incidental expenses. | |||||||||
