It has a mass much greater than had been previously expected - almost as great as a gold atom.

A project is under way to test that with gold atoms.

Let us suppose our stars were something interesting such as gold atoms.

Or, putting a price tag on it, a "universe" of gold atoms would only sell for around $7.50 at current prices.

At the beginning of the reduction process the gold atoms are liberated from the chloroauric acid.

Ultimately, a beam of gold atoms may be used.

Using the data from the experiments, the team calculated the mass of a single gold atom at 0.29 0.05zg-the actual value is 0.327zg.

This causes Au ions to be reduced to neutral gold atoms.

Did it interact with the gold atoms differently than other particles would have?

At these energies, colliding gold atoms are expected to pass right through each other, leaving between them a tiny region of concentrated energy.
