Use of a Linear Staircase Generator in Displaying Synchronized Pulse Activity
(The American Institute of Physics, 1968-09)
Flow Field of a Bunsen Flame according to Source Sheet Approximation
(The American Institute of Physics, 1965-09)
A volume source sheet plus a uniform flow is used to represent the flow field of a two‐dimensional Bunsen flame when the density ratio of the unburned to burned gases is 5.5. The unknown flame shape is determined by the ...
Analytical Formulation of Incremental Electrical Conductivity in Semiconductors arising from an Accumulation Space‐Charge Layer
(The American Institute of Physics, 1964-05)
Analytic expressions are derived which relate the incremental electrical conductivity in an accumulation layer on a semiconductor to the concentration of surface ions. The theory is checked both by comparing the predicted ...
Dipole—Quadrupole and Retardation Effects in Low‐Energy Atom—Atom Scattering
(The American Institute of Physics, 1964-09-01)
Simple approximation formulas are derived for the dipole—quadrupole and retardation effects upon the total elastic scattering cross section for atomic collisions in the thermal energy range. For a long‐range potential ...
``Floating Wire'' Technique for Testing Magnetic Lenses
(The American Institute of Physics, 1965-02)
Improvements in the well‐known technique of using a current‐carrying wire to simulate particle trajectories in a magnetic field are described. As presently used, the parameters of magnetic lenses can be determined for a ...
Failure to Bond Rupture and Nuclear Recoil Following (n, γ) Activation
(The American Institute of Physics, 1962-02-15)
Following the absorption of a thermal neutron by 127I or 79Br, the neutron‐binding energy is frequently released in the form of a gamma‐ray cascade. As a result of partial cancellation of gamma‐ray momenta, a small fraction ...
Empirical Correlations among Monohydride Bond Lengths
(The American Institute of Physics, 1965-06-15)
Planarity of the carbon chain in crystalline polyethylene
(John Wiley & Sons, Inc., 1967-01)
No Abstract.
Photovoltaic Effects in Rutile
(The American Institute of Physics, 1964-06)
The ultraviolet photovoltaic response of barrier‐layer cells formed from single‐crystal rutile has been investigated. Typical samples have response maxima at 3200 Å, a D* of 109 cm cps1∕2∕W, and time constants of 100 μsec. ...
