These same nuclei then collided with a foil of lead.

Nuclear fusion: The process by which two nuclei collide and coalesce to form a single, heavier nucleus.

Now they are learning to compute what happens when nuclei collide.

When the nuclei collide, Dr. Ludlam said, "there's a tremendous concentration of energy.

Once formed, nuclei collide to coalesce or agglomerate where temperature and species dictate the mechanism.

The process occurs when atomic nuclei in hot gases collide and fuse, or merge, a reaction that releases large amounts of energy.

The kinetic energy of fission products is converted to thermal energy when these nuclei collide with nearby atoms.

You can't steer them, so aiming for the point at which the nuclei (I think they're using gold) collide would be essentially impossible at this time.

Each nucleus collides millions of times with the others in a fleck-shot swirl like glowing snowflakes.

When two gold nuclei collide head on, the protons and neutrons dissolve into a tiny droplet.
