The Canonical Theory of Motion of a Charged Particle in a Slowly Varying Electromagnetic Field

Description: "The canonical theory of motion of a charged particle in a slowly varying, static electromagnetic field is formulated. The Hamiltonian is written down explicitly in terms of the coordinates of the gyration and the drift. The method of approach is analogous to that of the canonical formalism with subsidiary condition as used in theories of collective motion in many-body systems, such as the motion of the center of gravity. In the lowest order of the perturbation, it is shown that the Hamiltonian… more

Convergence of the Perturbation Expansion in Some Models of the Field Theory

Description: "It is shown that in a class of models of quantum field theory, the perturbation expansion of the resolvent operator, (H - z)-1, converges for all complex z. The class of models consists of all theories with Yukawa coupling in which the vacuum polarization is neglected. The method used is that of comparison with the exactly solvable neutral solar model."

Gravitational Instability and One-Component Plasma Oscillations

Description: "A kinetic study is made of a system of neutral particles which interact under gravitational forces. The Jeans instability is recaptured in the limit of long wavelengths where the growth rate assumes a characteristic maximum value. As the wavelength diminishes to a certain critical distance, the instability vanishes. This distance is consistent with thermal-gravitational estimates for the diameter of a star. Plasma oscillations are found in the central region of a one-component charged gas clou… more

The Scattering Constant for Doubly Charged Particles in Nuclear Emulsion

Description: "An experiment in which a nuclear emulsion stack of 25 Ilford G-5 emulsion pellicles were exposed to 925-Mev He^4 nuclei is described. The tracks of the He nuclei entering the stack were followed in the stack until they interacted or stopped. From the data the scattering constants for He^4 and He^3 were calculated."
