Nuclear Structure and Galactic γ-Ray Activity

The observation of galactic γ lines following the decay of radioactive nuclei provides a direct link between nuclear physics experiments in earth-based laboratories and astrophysical observations with space-based observatories. Two examples are presented to illustrate this interplay: the measurement...

description The observation of galactic γ lines following the decay of radioactive nuclei provides a direct link between nuclear physics experiments in earth-based laboratories and astrophysical observations with space-based observatories. Two examples are presented to illustrate this interplay: the measurement of the lifetime of (44)Ti to allow an improved determination of the (44)Ti mass of the supernova remnant Cassiopeia A from the observed γ ray activity and the measurements of excited states in (24)Si to determine the reaction rate of (23)Al(p, γ)(24)Si which might be important for a reduced production of (22)Na in novae.
