We have measured absolute differential and total cross sections for positrons scattered elastically from helium at energies from 44.9 to 84.7 eV. The results are compared with theory, and, in addition, the total elastic cross sections are compared wi

The stored energy released in Stage I recovery of reactor neutron irradiated copper was measured by differential thermal analysis calorimetry for three fluences up to a maximum of 3.5 × 1018 n/cm2 (E>0.1 MeV) after irradiation at temperatures of les

A ball that rolls on parallel tracks, whose width is less than the diameter of the ball, experiences both translational and rotational motions. The linear accelerations of the ball for cases of rolling and slipping are derived theoretically, and thes

Because the production of Frenkel defects occurs most readily along specific crystallographic directions in fee structures, the recovery mechanism by which annihilation occurs should also be related to the same crystallographic orientations. The reco

Characteristics of recovery processes have been investigated for cases of heating a sample to successively higher temperatures by means of isochronal annealing or by using a rapid pulse annealing. A recovery spectra shows the same features independen

Investigations have been made of how stage-I recovery depends on radiation doping and on the magnitude of the radiation dose for aluminum samples that were irradiated with 0.40-MeV electrons. Experimental results give (1) the amount of enhancement of

Thin copper and platinum single-crystal foils have been irradiated at liquid-helium temperature with electrons of energies between 1 and 3 MeV. From resistivity measurements the directional dependence of the damage rate was determined with high accur

Electron irradiations have been used to determine how the atomic recoil energy changes the stage-I recovery data on aluminum samples for the near-threshold energy region. Results indicate that the recovery spectrum of aluminum is quite similar to tha
