Abstract

Low-energy post-accelerated radioactive ion beams hive been used to study nuclear reactions addressing important nuclear structure and nuclear astrophysics questions. A high-granularity, large-solid-angle silicon strip detector array has been used to account for the low reaction products' yields. First experiments using a He beam on thin C targets show the feasibility of direct reaction studies with good angular resolution and a detection limit in access of 0.1 mb sr cross sections. The measurement of the six α-decay channel in a N-induced reaction on a B target shows the capabilities of this experimental technique even for sophisticated reaction studies. The study of stellar properties in ground-based experiments, in particular break-out reactions from the hot-CNO, i.e. O(α, ν) Ne, can be pursued using these beams. Experiments are being performed to study these reactions by measurement of d( Ne, p) Ne*(α) O and α( Ne. p), which might provide an alternative breakout route.
