Description
The storage ring facility, DESIREE, is briefly introduced and two examples of experiments and their astrophysical implications are discussed. 1: Mutual-neutralization reactions between negative hydrogen and positive metal ions are studied in DESIREE to aid quantitative analysis of abundances of such metals from stellar spectra. 2: Polycyclic aromatic hydrocarbons (PAHs) are believed to be ubiquitous in interstellar space. We have studied the stability of PAH fragments formed exclusively in collisions taking place at stellar-wind velocities by storing such collision products in DESIREE for up to seconds or minutes.
