Some of these gamma rays pass near atomic nuclei, in the process transforming into an electron and a positron, researchers said.

某些伽马射线在靠近原子核的附近经过，进入到转化为个电子和正电子的过程，研究人员说。

These high-energy gamma rays, detected by Fermi’s Large Area Telescope (LAT), have wavelengths one-thousandth the size of an atomic nucleus.

这些“费米大天区望远镜（LAT）”所侦测到的高能伽马射线的波长仅相当于原子核大小的千分之一。

Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

Using the first completed section of the NOvA neutrino detector, scientists have begun collecting data from cosmic rays-particles produced by a constant rain of atomic nuclei falling on the Earth's atmosphere from space .
