The transmission of gamma radiation from a "point isotropic" source of cobalt-60 through iron and lead has been measured out to a thickness of approximately 15 mean-free-paths. The dose build-up factors derived from the observed transmissions agree satisfactorily with the calculations based on...
An asymptotic theory of liquid He 3 — He 4 mixtures is presented, in which the component fluids are described, approximately, in terms of ideal symmetric and antisymmetric fluids. The theory yields results in at least semiqualitative agreement with the data if the antisymmetric fluid is taken...
The phenomenon of vacuum polarization can be studied apart from other higher-order electrodynamic effects through its modification of the electrostatic interaction of heavy charged particles. In particular the principal deviations of the 2 p - 1 s level separations from the Bohr formula in light...
Arguments are given to show that the laws that determine the motion of the ether should not refer to the motion of anything that is not in the immediate vicinity of the point whose motion is being considered. From this assumption and from Newton's laws of gravitation, the equations of motion of...
154 analyzable three-prong events were observed in collisions between Cosmotron-produced neutrons, with energies up to 2.2 Bev, and protons in a hydrogen-filled diffusion cloud chamber. These events were classified as a result of the reactions n + p → p + p + π - , p + p + π - + π 0 , and p...
The polarization of deuterium for 314-Mev protons has been examined as a function of angle. A beam of 314-Mev protons about 60 percent polarized was scattered by a liquid deuterium target. Measurements were made of the asymmetry of scattering of fast protons, namely both elastically and...
Granular inclusions, grain boundaries, lamellar precipitates, and the crystalline surface have been examined as possible nucleation centers for domains of reverse magnetization in ferromagnetic materials. It is concluded that the surface density of magnetic poles at the grain boundaries ω * is...
