The scattering of neutrons with energies of less than or approximately 1.5 MeV from tantalum, rhenium, and platinum was studied experimentally. Elastic and inelastic neutron-scattering angular distributions were determined at incident neutron-energy intervals of less than or approximately 20 keV throughout th range 0.3 to 1.5 MeV. Time-of-flight measurements were made concurrently at eight or more scattering angles between 25 and 155 degrees with sufficient scattered neutron-energy resolution to separate the elastic scattered component from most inelastic scattered neutron groups. Differential inelastic scattering cross sections were observed corresponding to the excitation of various states. The experimental results were compared with calculations based upon the optical model and the Hauser-Feshbach formula inclusive of corrections for resonance-width fluctuations. The experimentally observed level structure is discussed in the context of single-particle and rotational states of deformed nuclei.

附註: | Cover title. "July 1967." Includes bibliographical references (p. 10). An investigation has been conducted in the Langley full-scale tunnel to determine the aerodynamic characteristics of a full-scale model employing a sailwing concept and having a wing aspect ratio of 11.5. The wing had a rigid leading-edge spar, rigid root and wing-tip ribs with a trailing-edge stretched between these ribs, and a fabric covering stretched between the leading and trailing edeges. The fabric of the sail maintained a smooth airfoil contour over the installed angle-of-attack range, but some rippling occurred at the trailing edge near the wing root as the wing stalled. The aerodynamic characteristics of the sailwing, in particular the maximum lift and maximum lift-drag ratio, compared favorably with those of conventional hard wings. A lateral-control device based on the wing-warp principle was effective at angles of attack below that for wing stall, but at angles near stall, the control effectiveness became low and nonlinear. |
