Astrophysical constraints from gamma-ray spectroscopy

Diehl, Roland; von Ballmoos, Peter; Prantzos, Nikos

Gamma-ray lines from cosmic sources provide unique isotopic information, since they originate from energy level transitions in the atomic nucleus. Gamma-ray telescopes explored this astronomical window in the past three decades, detecting radioactive isotopes that have been ejected in interstellar space by cosmic nucleosynthesis events and nuclei …
