Nuclear Decay Schemes in the Actinium Family (open access)

Nuclear Decay Schemes in the Actinium Family

Abstract: "With magnetic alpha-particle and electron high-resolution spectrographs and scintillation gamma-ray spectrometers, a study was made of the nuclear decay of a number of members of the actinium family - U-235, Th-227, Ra-223, Em-219, Po-215, and Bi-211. Decay schemes are presented for each of these nuclides, together with such correlations as are possible with present theoretical nuclear models. The decay scheme of U-235 and a portion of that of Th-227 are interpretable in terms of the collective model and a spherical shell-model characteristics; however, the intermediate nuclides present complexities not well understood."

Note on Possible Stabilization Due to Coupling

Abstract: "By a simple illustration it is pointed out that, conceivably, the real coupled character of the general magnetohydrodynamic equations may lead to much slower instability growth rates, if not stabilization, than predicted from the linearized set of equations."

An Enhanced Magnetic Mirror Machine (open access)

An Enhanced Magnetic Mirror Machine

Abstract: "A dc magnetic mirror machine has been built and tested by the ARC Research Group. Radiofrequency enhancement has been included in the design through the use of rf plates in the vacuum chamber of the machine. For the proton beams of the order of 1[mu]a, the mirror action has been observed as a function of both the rf voltage and the magnitude of the mirror field relative to the main magnetic field. Current measurements were performed with the aid of a Faraday cup with suitable bias grids."

Electron-Population Analysis and the Dipole Moment of the LiH ¹Σ⁺ Excited State / A.M. Karo (open access)

Electron-Population Analysis and the Dipole Moment of the LiH ¹Σ⁺ Excited State / A.M. Karo

Abstract: "Detailed consideration is given to some properties of the first excited electronic state. Following the analysis proposed bv Mulliken, SCF LCAO-MO coefficients are used to obtain qualitative information about the electron distributions. Comparison is made with earlier work with respect to the description of the excited-state dipole moment, the effective electric moment between the ground and excited states is also calculated. From this, the oscillator strength for the first allowed transition is computed as a function of the internuclear distance."

Laboratory Production of Fine Grain Nuclear Emulsion (open access)

Laboratory Production of Fine Grain Nuclear Emulsion

Abstract: "Nuclear emulsion has been made in a manner similar to that of Demers and of Perfilov. An attempt has been made to achieve the grain size and sensitivity of Perflov's type P-9 Sensitive emulsion. Silver bromide grain sizes of essentially the same average size as Perfilov's were made from precipitations carried out over a narrow range of pAg's. Three brands of gelatin were tried. High sensitivity has not been achieved."

A Note on the Optical Potential with the Pauli Principle (open access)

A Note on the Optical Potential with the Pauli Principle

Abstract. The idea of determining potentials from phase shifts is here called the "optical model" while the construction of an effective single particle scattering potential from the known two-body forces is called the "optical potential." A novel method is given for construction of the optical potential with the Pauli principle and its difficulties are pointed out. In the Appendix one connection between the optical potential and optical model is given.

Stresses and Deflection in a Cylindrical Shell Subjected to Concentrated Radial Loads (open access)

Stresses and Deflection in a Cylindrical Shell Subjected to Concentrated Radial Loads

Abstract. The measured stresses and deflections of cylindrical shells with free ends, when subjected to concentrated loads along the central diameter, are presented. An empirical analog is made with a simply supported flat plate for which stresses and deflection are easy to compute. Over the range of parameters studied (ratio of cylinder diameter to wall thickness varied from 32 to 64, ratio of cylinder length to diameter varied for. 0.6 to 5) the agreement is such that the empirical results should have useful application in the design of shells for local loading.

Silver Bromide Crystal Size Distribution as Influenced by Gelatin Concentration in Producing Nuclear Emulsion (open access)

Silver Bromide Crystal Size Distribution as Influenced by Gelatin Concentration in Producing Nuclear Emulsion

At the Montreal colloquium Ahmed urged Oliver to make batches of emulsion which would differ only in gelatin concentration. At that meeting Oliver had reported finding a correlation between grain size and silver ion concentration during precipitation, as implied by Perfilov and his Leningrad colleagues. Ahmad felt that one should have more precise knowledge of the relative influence of gelatin concentration of grain sized and their distribution. The incentive is that, in spite of excellent progress in many laboratories and in consistently dependable production from industry (to us, of course, Ilford is most familiar), nuclear emulsions are needed in a wider variety of sensitivities and grain sizes. Available nuclear emulsions have limitations in sensitivity, discriminatory ability, and concentration of hydrogen nuclei. Fine grain size enhances discriminatory ability. An incentive is also in that there is a shortage of literature dealing with the processes involved in the fundamental steps of emulsion production.
