TLDR
In this paper, heavy ion sputtering is a powerful method for the production of thin films of refractories, and both supported and self-supported films have been made, and the purity of the targets depends mainly on the purity in the starting material.About:

Sputtering yield measurements
TL;DR: The conditions for performing reproducible sputtering measurements are a well-defined ion beam with high enough current and uniform current density, a low enough vacuum and a well characterized target as discussed by the authors, and different methods to determine total and differential sputtering yields, i.e., the measurement of the loss of target material and the flux of sputtered atoms, are outlined.

Sputtering of multicomponent materials
TL;DR: A survey of the knowledge of preferential sputtering of certain species in multielement materials, the subsequent formation of a near surface layer with altered composition, the total sputtering yields as a function of composition after steadystate conditions are established, and the angular ejection distribution of different species is given in this paper.

Fusion cross sections for the 16O + 16O reaction
TL;DR: In this article, the fusion cross section for the 16O + 16O reaction was measured with a time-of-flight technique at energies Elab = 35, 45, 52, 60, 70 and 80 MeV.

Deposition techniques for the preparation of thin film nuclear targets
TL;DR: In this article, the basic principles that regulate vacuum evaporation and the physical processes involved in thin film formation are discussed, and the principal methods of heating the evaporant are detailed and the means of measuring and controlling the film thickness are elucidated.

Analysis of the primary process in isotope sputtering
V.I. Shulga,Peter Sigmund +1 more
TL;DR: In this paper, the authors investigated the influence of key input parameters on the relative sputter yields of isotopic mixtures with respect to the surface scattering effect, with the notable exception of the target-target interatomic potential, the surface barrier, and the treatment of nonbinary collisions.

Self-supporting metal foils prepared from the oxides of the separated isotopes of rare earth elements
L. Westgaard,S. Bjørnholm +1 more
TL;DR: In this article, the results of the separated isotopes of Yb, Sm, Dy, Er, Nd, Gd and Lu were obtained from the oxides in batches of 20-40 mg by reduction in vacuo with lanthanum or thorium metal powder.
