Abstract
The recoil separator ERNA (European Recoil Separator for Nuclear Astrophysi cs) for improved measurements of the astrophysical key reaction C-12(alpha, gamma)O-16 is being developed at the 4 MV Dynamitron tandem accelerator in Bochum to detect directly the O-16 recoils. The total detection efficiency of about 50 % allows direct measurements in a much wider energy range than previously accessible. In addition this technique allows improved measurem ents not hampered by cosmic background problems when compared to gamma -ray detection.
