Measuring Cosmic Elements with Gamma-Ray Telescopes

Diehl, Roland

Gamma-ray telescopes are capable of measuring radioactive trace isotopes from cosmic nucleosynthesis events. Such measurements address new isotope production rather directly for a few key isotopes such as ⁴⁴Ti, ²⁶Al, ⁶⁰Fe, and ⁵⁶Ni, as well as positrons from the β⁺-decay variety. Experiments o…
