The following report studies uranium ore deposits discovered in the Browns Park Formation, south-central Wyoming and northwest Colorado.

"This paper summarizes the results of the field studies of the Survey's Reconnaissance Group and outlines some geologic criteria that may be useful in guiding the search for uranium ore. The writers wish to acknowledge the cooperation of the minding companies and individuals who materially aided the program of investigations by reporting radioactive localities and by submitting samples of radioactive rocks and ores."

The main thrust of this work was directed to the task of determining the thermodynamic behavior of condensed solids and fluids containing simple molecules. Properties calculated include specific heats, equations of state, compressibilities, sound velocities, virial coefficients, viscosities, and thermal expansion. In addition, details of the structural, orientational, and magnetic phase transitions were determined. Dynamical quantities calculated include the lattice, libron, and vibron mode frequencies at various pressures and temperatures. Also, we developed new techniques required to meet our objectives. One was a method for accurately calculating the Gibbs free energy of various phases. Another is the multiple-histogram Monte Carlo which can dramatically reduce computing time and can provide a continuous map of thermodynamic averages over a range of some thermodynamical variable.

Focus has been mainly on preparation and characterization of triply bridged dinuclear complexes containing a tris-2-2`- bipyridineruthenium chromophore and a second tris-bipyridine metal complex which is to serve as electron donor or acceptor, and of linked RuL{sub 3}-containing D-C-A complexes where D is a phenothiazine donor and A is a diquat type acceptor.
