@Atomic var counter: Int = 1 Conclusion The property wrappers are an extremely powerful feature that helps you to get concise and reusable code for the properties you write. In this article, we’ve discussed only one of the many possible use cases. Feel free to follow me on Twitter and...
Vacuum-sublimated C-60 films (around 1 mu m thick) are bombarded with fast atomic ions (He-4, C-12, O-16, S-32, Br-79; I-127) in the range from 2 to 80 MeV. The initial velocity of the primary ions is kept constant at 1.1 cm/ns, in order to maintain the s...
