The objective of the meeting was to provide a companion meeting to the ''First Symposium on Accelerator Radiation Dosimetry and Experience'' which was held November 3-5, 1965, at the Brookhaven National Laboratory. This first symposium was limited in scope to an intensified discussion of dosimetry techniques. The biology which is associated with high energy radiation was specifically excluded, since it was the original plan to hold a second symposium devoted entirely to biology. Thus the present Symposium was a sequel to the first and they were inseparable in their objectives. Since those attending the BNL Symposium were almost entirely health physicists with a background in physical science and actively engaged in the solution of radiation protection problems at high energy accelerators, it was felt that it would be necessary to begin the BID Symposium with a general review session on radiation biology, in order to provide a biological background for the proper understanding of the later sessions. This first session was arranged to give the health physicist a meaningful transition from fundamental radiobiological considerations to current new research activities in high energy biology. In our opinion, and also based on the comments of several of those attending these objectives were …

Article provides a tribute to the life and career of Cyrus Stevens Avery, who served as State Highway Commissioner of Oklahoma, Director of the Tulsa National Bank, and a member of the Board of Directors of the Tulsa Chamber of Commerce.

Article discusses the establishment of Christianity and mission schools among the Choctaws in the early nineteenth century. Arminta Scott Spalding provides context through a description of the history of the Natchez Trace and the Choctaw Nation.

Article includes the reminiscences of the author's grandmother living on the frontier of the Choctaw Nation in Indian Territory, as well as the author's own memories of her grandmother. Becky Berry's grandmother, Mrs. H. H. Berry, describes growing up and traveling around, early education, and family memories.

This section includes the minutes of the quarterly meeting of the Board of Directors of the Oklahoma Historical Society that was held on January 26, 1967.

Article explores Henry C. Brokmeyer's sojourn among the Muscogee (Creek) tribe. Donald K. Pickens examines the life of the lawyer, politician, and Hegelian philosopher and his fascination with the Muscogees.

Notes and Documents column including a document about recollections of writer Clarence Alva Powell of his life in Indian Territory in the towns of Ashland and Wilburton.

Article discusses the ideas present in Oscar Ameringer's theories of agrarian socialism and its place in Oklahoma society. H. L. Meredith explores his impact as a leader of the Socialist Party in Oklahoma, organizer, and author of socialist literature.

Article describes relations between the United States government and the Chickasaw Nation regarding the large number of Chickasaw freedmen that stayed in the nation after their emancipation. The Chickasaws had several issues with the freedmen drawing other freed peoples to the area and becoming the racial majority.

Article describes the need for and establishment of Spencer Academy in the Choctaw Nation. W. David Baird explores the leadership behind the institution, its religious connections, events during the Civil War, and the rebuilding of the academy after it burned down.

Article describes the life and work of Baptist minister Sylvester Witt Marston, who spent time preaching in frontier towns of Indian Territory, leading missions, working as an agent at the Union Agency, and establishing schools for freedmen.

A Planck law relationship between absorption and emission spectra is used to compute the fluorescence spectra of some photosynthetic systems from their absorption spectra. Calculated luminescence spectra of purple bacteria agree well but not perfectly with published experimental spectra. Application of the Planck law relation to published activation spectra for Systems I and II of spinach chloroplast permits independent calculation of the luminescence spectra of the two systems; if the luminescence yield of System I is taken to be one-third the yield of System II, then the combined luminescence spectrum closely fits published experimental measurement. Consideration of the entropy associated with the excited state of the absorbing molecules is used to compute the oxidation-reduction potentials and maximum free-energy storage resulting from light absorption. Spinach chloroplasts under an illumination of 1 kilolux of white light can produce at most a potential difference of 1.32 eV for System I, and 1.36 eV for System II. In the absence of non-radiative losses, the maximum amount of free energy stored is 1.19 eV and 1.23 eV per photon absorbed for Systems I and II, respectively. The bacterium Chromatium under an illumination of 1 milliwatt/cm{sup 2} of Na D radiation can produce at most a …

The energy and angular distributions of N{sub 2}H{sup +} and N{sub 2}D{sup +} formed when a beam of N+2 passes through a scattering cell containing H{sub 2}, D{sub 2}, or HD have been measured at relative kinetic energies ranging from 2.3 to 11.6 eV. From some experiments, intensity contour maps that show the complete product velocity vector distribution in the centre of mass system have been generated. Although backward recoil scattering occurs at all energies, most products are scattered forward in the centre of mass system. The shape and position of the forward scattered product peak are largely consistent with the stripping model modified to account for target motion.
