Nineteen gamma-ray transitions found in 151Eu are interpreted as decay branches from levels of 195.8, 196.5, 243.0, 306.8, 500.0, 503.1, 578.0, 600.6, 719 and possibly 696, 781 and 906 keV. In 153Eu ten gamma rays were found and are interpreted as decays from levels of 83.3, 151.3, ...

Gamma-ray astronomy has been one of the prime scientific research fields of the Max-Planck Institute for Extraterrestrial Physics (MPE) from its beginning. Over the years, the entire gamma-ray energy range accessible from space was explored. The purpose of this review article is to summarise the...

Furthermore, the gamma-ray spectrum of V4641 Sgr is among the hardest TeV spectra observed from any known gamma-ray source and is detected above 200 TeV. Gamma rays are produced by particles, either electrons or protons, of higher energies. Because energetic electrons lose energy more ...

form of weakly interacting massive particles (WIMPs), dark-matter particles can annihilate into gamma-ray photons and other Standard Model particles. Significant effort is therefore being spent in searches for dark-matter annihilation signals in the gamma-ray band, including searches towards the Milky...
When I was younger, I used to love nothing more than staying up all night in the cathode ray glow of the television with a bottle of caffeinated beverage by my side, watching such late night fare as Incredible Hulk reruns, badly dubbed kung fu flicks, and rubber suited monster movies. Th...
Gamma-ray angular distributions, nγ angular correlations, γγ coincidences and Doppler-shift attenuations have been measured in the 42Ca( α, nγ) 45Ti reaction. In addition to the known positive-parity levels forming the K π = 3 2 + band, the K π = 1 2 + band members are ...
