  Poly- and single-crystal thin films of U-Mo alloys have been grown both on
glass and sapphire substrates by UHV magnetron sputtering. X-ray and Electron
Backscatter Diffraction data indicate that for single-crystal U1-xMox alloys,
the pure cubic uranium gamma-phase exists for x > 0.22 (10 wt.% Mo). Below 10
wt.% Mo concentration, the resulting thin film alloys exhibited a mixed
alpha-gamma uranium phase composition.
