There was a brief silence; then one of Dr. Schloss's technicians said, in a neutral voice: "Pi-m$oA shower from the iron nucleus.

The interior is a lattice of buckytubes - carbon -laced with iron nuclei.

Occasionally, as in the purple slates of North Wales, ferrous reduction spheres form around iron nuclei, leaving a light green spotted texture.

In any given nanosecond, the car knew its position to within the diameter of an iron nucleus, and its body was sprinkled with delicate lasers that were nearly as precise.

In particular, models suggested that shock waves from the nearby M87 galactic jet could accelerate an iron nucleus to ZeV ranges.

The most dangerous GCRs are heavy ionized nuclei such as Fe +26, an iron nucleus with a charge of +26.

The most energetic particles are cosmic rays: iron nuclei fleeing the explosions of stars, moving close to the speed of light.

The iron nucleus cannot fuse with other nuclei.

A critical situation arises when iron accumulates in the core, since iron nuclei are incapable of generating further energy through fusion.

Next came the mantle-two kilometers of neutrons and iron nuclei that became more neutron-rich with depth.
