Electron Microscope Observations of Fission Fragment Tracks in Thin Films of UO2

Publikováno v: Journal of Applied Physics. 31:2199-2208

Electron microscope studies of the tracks produced by fission fragments in thin films of UO2 have established a 100% detection efficiency for fission events in films 100 A or less in thickness. A background texture decreases the efficiency in thicker

Electron Microscope Studies on the Etching of Irradiated Germanium

Autor: T. S. Noggle, J. O. Stiegler

Publikováno v: Journal of Applied Physics. 30:1279-1288

Electron microscope and electron diffraction studies on the surfaces of CP‐4 etched germanium specimens have shown that the changes in etching behavior induced by fast neutron irradiation occur as a result of a gross change in chemical behavior and

Effect of Channeling on Damage Rates Associated with Heavy-Ion Irradiation of Gold

Autor: T. S. Noggle, J. H. Barrett

Publikováno v: physica status solidi (b). 36:761-774

Electron microscope studies of radiation damage produced by 60-MeV iodine ions in thin gold crystals have been made to determine the dependence of damage rate on orientation of the ion beam relative to [011] and (111). Experimental values of the mini

Fission Fragment Tracks in Metal Films

Autor: J. O. Stiegler, T. S. Noggle

Publikováno v: Journal of Applied Physics. 33:1726-1730

Fission fragment tracks observed in electron microscope studies of platinum and palladium films are interpreted in terms of thermal processes involving melting and vaporization. The results require that the energy lost by the fragment be converted in

Electron Microscopy of Aluminum Crystals Deformed at Various Temperatures

Autor: J. S. Koehler, T. S. Noggle

Publikováno v: Journal of Applied Physics. 28:53-62

99.994% pure aluminum single crystals were deformed in tension at 4.2°K, 78°K, and 295°K. The deformation at 4.2°K produced fine slip, observed by electron microscopy, and gave rise to a linear stress strain curve. At 78°K at low strain one agai

Low‐Temperature Reactor Irradiation Effects in Metals

Autor: T. H. Blewitt, R. R. Coltman, C. E. Klabunde, T. S. Noggle

Publikováno v: Journal of Applied Physics. 28:639-644

The effects of structural and chemical defects on the low‐temperature (30–50°K) annealing peak in low‐temperature reactor‐irradiated aluminum and copper were studied. From the fact that the density of reactor‐induced defects did not affect

High−energy neutron sputtering yields from gold and niobium

Autor: M. J. Saltmarsh, G. J. Smith, R. E. Reed, L. H. Jenkins, T. S. Noggle

Publikováno v: Applied Physics Letters. 26:426-428

High−energy neutron sputtering yields ≲10−4 ejected particles/ incident neutron have been measured for Au and Nb specimens irradiated under high−vacuum conditions using a neutron source based on the 9Be(d,n) reaction. These measurements are c

Victawet and Sodium Metaphosphate as Parting Agents for Electron Microscope Replicas

Autor: T. S. Noggle, J. O. Stiegler

Publikováno v: Review of Scientific Instruments. 32:406-408

It is shown that the active material obtained in the use of Victawet as a parting layer for electron microscope replicas is the inorganic decomposition product sodium metaphosphate (S.M.P.). The results of an investigation of the parting layer charac

Evidence for Dislocation Reactions in Copper

Autor: T. S. Noggle, F. W. Young

Publikováno v: Journal of Applied Physics. 31:604-606

Observations of slip lines and etch pits at dislocations on a copper crystal hardened by irradiation and deformed by bending are interpreted in terms of dislocation reactions.
