Calibration of G.M. Counters For Direct Counting of Radon in the Atmosphere

Description: An experiment has been carried out for the direct calibration of a Geiger-counter immersed in a balloon containing a known concentration of radon in equilibrium with its daughters. A theory was developed for finding out the geometrical efficiency of the counter used in this way, and for checking the experimental results with theoretical efficiency. The counters calibrated in this way may be useful for the direct measurement of radon in uranium mines and may also be useful for monitoring radioac… more

Local Fields With Terminating Expansions (x)

Description: "The quantum theory problem of constructing explicitly a local Lorentz invariant model field theory which has an asymptotic particle interpretation and gives rise to an S matrix different from unity is discussed. It is proved that if a local covariant field H(x) has a complete current, the S matrix associated with this field is identically equal to unity. Results show that in order to get an interaction, the current is not allowed to have a terminating expansion in terms of a free field. The ab… more

Remark on the Radiative Muon Decay in the Theory With an Intermediate Vector Meson

Description: "The problem of explaining the lack of radiative muon decay in an intermediate charged vector meson theory is discussed. A possible way of introducing the charged vector meson to the theory of weak interactions is outlined in which renormalization is retained. However, if this way is used, the anomalous magnetic moment is calculated to be large, which is in contradiction with expectation."

The Influence of Isotopic Composition on the Maximum in the Cosmic Ray Energy Spectra

Description: "The previously found maximum in the cosmic radiation energy spectrum is discussed, and the possibility that it arises in part from a misinterpretation of the data due to oversimplifying assumptions about the composition of the beam is examined. The importance that lack of recognition of isotopic composition may have is pointed out, and it is clear that this importance is strongly dependent on the measurements made and on the cut-off rigidity."

The Nature of the Axioms of Relativistic Quantum Field Theory

Description: "The formulation of field theories by means of Wightman functions is studied. It is shown that, given two field theories that satisfy all the axioms, one can construct a family of Wightmsn fields with the same properties by a process of superposition of Wightman functions. The condition of unitarity is formulated without reference to asymptotic conditions, and it is proved that the Wightman fields constructed by the superposition process (starting with "unitary" fields) fail to preserve unitari… more

A Theory of Hyperfragments

Description: "Mesic decay of hyperfragments is discussed systematically on the basis of a previous model for hyperfragments. The general formalism for the two-body and three-body mesic decay was developed. The polarization-direction correlation and the angular correlation for the two-body and the three-body decays are discussed together with the decay probability. The formalism was developed so as to include the isotopic spin selection rule ( DELTA I = 1/2 and 3/2) for the mesic decays. The theory was appli… more

Iteration Methods for Non-Linear Problems

Description: The methods of successive displacements or relaxation methods are investigated for a class of nonlinear problems. In particular it is shown that these methods are applicable to a large class of nonlinear problems arising from variational problems which yield elliptic equations. Constructive existence and uniqueness theorems are presented for the discrete problem and criteria are given for a practical method of obtaining solutions. The example of a discrete Plateau problem is used to illustrate … more

Containment in Cusped Plasma Systems

Description: "A survey of the current theoretical picture of plasma containment in cusped magnetic configurations is presented together with a mention of the points of contact which exist or might soon be made to exist with experiment. A theory of containment was developed which is applicable to the whole range of plasma densities from a tenuous plasma in an essentially vacuum magnetic field to a fully developed plasma which completely excludes the magnetic field from its interior. Also presented are cursor… more

Alternating Direction and Semi-Explicit Difference Methods for Parabolic Partial Differential Equations

Description: "The energy method is applied to study the stability of two types of difference approximations to parabolic partial differential equations, the alternating direction methods Douglas, Peaceman, and Rachford, and a new semi- explicit method. Each difference scheme is proved to be unconditionally stable. These results apply to parabolic equations with variable coefficients, defined in cylindrical domains with an essentially arbitrary bounded base."

The Motion of a Charged Particle Near a Zero Field Point

Description: "The behavior of charged particles in a plasma-free cusp field, or in a cusp field where there is very little plasma, is studied. The numerical computations described may provide a valid picture of the behavior of particles outside such a body of plasma or in the early stages of creation of such a cusped plasma in the low- beta limit. The computations provide a striking illustration of orbits which neither have constant magnetic moment nor behave so irregularly as to defy explanation."
