"These efforts promise to shed light on the disk-jet connection and uncover the origins and mechanisms behind the gamma-ray photon emission." The relativistic jet examined by the researchers is ...

Gamma rays originate from a variety of sources in ... The electron won't budge until it absorbs a photon with the ionization energy. Just one photon with the necessary ionization energy can ...

The "cosmic pinwheel" that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

Building on Eugen Sänger’s ideas, scientists are developing photon propulsion by annihilating matter and antimatter, creating gamma ray avalanches to power spacecraft into the cosmos.

Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly ...

against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to calibrate therapy electron beams, as well as relative dose measurements for photon ...
