The authors report on measurements of the angular momentum of an autoionizing level of uranium obtained by using the technique of resonant ionization polarization spectroscopy. This requires that the ion yield is measured as a function of the polariz

A theoretical and experimental study of resonantly enhanced two-photon absorption in 238U vapour excited by two continuous wave dye lasers is presented. Good quantitative agreement between theory and experiment is found. In particular the central pre

The authors examine the Doppler profile of a collimated effusive atomic beam for two situations of experimental interest. First, they show that there is an advantage in making the source and collimating slit of comparable size. Secondly they discuss

A method for examining the hyperfine structure of uranium is described. By using a double-resonance technique with two scanning single-frequency continuous-wave dye lasers and a television-type data display, the measurements are essentially. Doppler-

This work determines the thermal microwave emissivity of a plasma of infinite extent, in which there is a linear gradient of electron number density in the direction of observation. The region in the plasma which contributes most effectively to the r

Ray-optic theory is applied to a collisionless strongly deviating turbulent plasma to determine the microwave power transmitted through the plasma. The transmission coefficient is calculated for two cases: (1) The `Fraunhofer' region, in which the re

The ZETA plasma is believed to contain field-aligned irregularities in density, loosely called turbulence. Such irregularities cause scattering of a microwave beam traversing the plasma, and will also affect the emission of thermal microwave noise. T

The Tokamak confinement system is one of the more successful devices on the road to controlled fusion. It is simple both in concept and construction, and has produced the closest approach to a reactor-type plasma of any confinement system so far. How
