NASA's Fermi Gamma-ray Space Telescope has been mapping out the high-energy sky for several years. Here, Fermi scientists list 10 of their favorite gamma ray sources, from supernovas to black

1992-10-01 · Gamma-ray energies of 152 Eu were measured with the uncertainties of 1.1–7.3 eV in the region of 290–720 keV using Ge spectrometers. To determine the 719 keV γ-ray energy of 152 Eu, we measured the 125 and 592 keV cascade γ-ray energies of 185 Os which provide the 717 keV cross-over γ-ray energy.

L’europium 152 se d´esint`egre par capture ´electronique (72,1%) et par ´emission de positron (environ 0,027%) This is a table of commonly-observed gamma energies, arranged by increasing gamma energy. The parent isotope and its half life are listed with the gamma energy. The key gamma energy for an isotope has an asterisk following it. Each isotope is listed once with its complete set of gamma energies. The gamma decay fraction Gammas from 152Eu (13.537 y 6) Eg (keV) Ig (%) Decay mode.

The Moon shines brightly in gamma rays as seen in this time sequence from NASA’s Fermi Gamma-ray Space Telescope. Each 5-by-5-degree image is centered on the Moon and shows gamma rays with energies above 31 million electron volts, or tens of millions of times that of visible light. Europium 152 and Europium 154. This excellent spectrum was kindly provided by Christoph Denk, an uncommon isotope to get hold of, Eu152 and Eu154 is a man made isotope, and has a half life of 13.5 years. This Spectrum was recorded with GS-1100A and a Harshaw Scintillation Detector.
