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."

A Proposed Particle Containment Device (open access)

A Proposed Particle Containment Device

Abstract: A device is proposed for confining charged particles to a localized region of space by means of the alternating electric field of a resonant cavity. The motion of single electrons in the field is stable. The limitations to particle density and temperature are discussed, and found to be too severe to allow the device to serve as a reactor, although it might be a useful laboratory tool.

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

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."

The Production of Deuterons in High-Energy Nucleon Bombardment of Nuclei, and Its Bearing on Nuclear Charge Distribution (open access)

The Production of Deuterons in High-Energy Nucleon Bombardment of Nuclei, and Its Bearing on Nuclear Charge Distribution

Thesis discussing the study of deuterons produced at wide angles to a beam of 300 Mev neutrons and a beam of 300 Mev protons. It was observed that the deuterons are formed by "a two step process in which the incident nucleon, or its collision partner, is scattered and then picks up in the same nucleus." Some tritons are also observed, and it is thought that they are formed by the same process as the deuterons. From these findings, the author concludes that "for heavy nuclei, there is a nuclear skin rich in neutrons."

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

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."
