WebSep 12, 2024 · A Kα X-ray is produced by the transition of an electron in the L ( n = 2) shell to the K ( n = 1) shell. An electron in the L shell “sees” an effective charge Z = 13 − 1 = 12, because one electron in the K shell shields the nuclear charge. (Recall, two electrons are not in the K shell because the other electron state is vacant.) WebNov 18, 2014 · The represented observatories are: HESS, Fermi and Swift for gamma-ray, NuSTAR and Chandra for X-ray, GALEX for ultraviolet, Kepler, Hubble, Keck (I and II), SALT, and Gemini (South) for visible, Spitzer, Herschel, and Sofia for infrared , Planck and CARMA for microwave, Spektr-R, Greenbank, and VLA for radio.

WebMar 19, 2024 · There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The … WebGamma-ray bursts were first detected by accident. Gamma rays are also produced by nuclear explosions, so in 1963, the U.S. military launched satellites to scout for detonations, which the Nuclear Test Ban Treaty prohibited. Researchers soon realized that they were detecting gamma-ray emissions from outer space, not Earth. WebGamma rays are produced in copious quantities in the upper atmosphere of the Earth as a consequence of cosmic-ray interactions. Balloon experiments rely typically on the “growth curve” technique to estimate the contribution of atmospheric gamma rays to the observed event count rate. black miss ohio
