Anisotropic Relaxation Time for Solids with Ellipsoidal Fermi Surfaces (open access)

Anisotropic Relaxation Time for Solids with Ellipsoidal Fermi Surfaces

Many solids have Fermi surfaces which are approximated as ellipsoids. A comprehensive solution for the magnetoconductivity of an ellipsoid is obtained which proves the existence of a relaxation time tensor which can be anisotropic and which is a function of energy only.

Cross Section Measurements in Praseodymium-141 as a Function of Neutron Bombarding Energy (open access)

Cross Section Measurements in Praseodymium-141 as a Function of Neutron Bombarding Energy

Using the parallel disk method of activation analysis, the (n,2n) reaction cross section in 141-Pr was measured as a function of neutron energy in the range 15.4 to 18.4 MeV. The bombarding neutrons were produced from the 3-T(d,n)4-He reaction, where the deuterons were accelerated by the 3-MV Van de Graff generator of the North Texas Regional Physics Laboratory in Denton, Texas.

Investigation of the Uniaxial Stress Dependence of the Effective Mass in N-Type InSb Using the Magnetophonon Effect (open access)

Investigation of the Uniaxial Stress Dependence of the Effective Mass in N-Type InSb Using the Magnetophonon Effect

The magnetophonon effect was used to investigate the uniaxial stress dependence of the effective mass in n-type InSb (indium antimonide).

Phase Shift Determination for Elastic Potential Scattering, Using the IBM 360-50 Computer (open access)

Phase Shift Determination for Elastic Potential Scattering, Using the IBM 360-50 Computer

The primary objective of this paper is to present a computerized method for the extraction of phase shifts from an angular distribution. This was accomplished using a least squares curve fitting routine.
