Scientific paper
The paper analyzes the explosive nuclear processing associated with the passage of a supernova shock through the helium-burning shell of a massive presupernova star, and, in particular, examines the resulting heavy (A greater than or equal to 60) element yields. It is concluded that the derived final heavy element yields do not mimic the typical solar-system r-process abundance curve and do not appear able to account for the observed meteoritic heavy element anomalies. Such a failure is essentially due to a huge overproduction of the nuclei around A 78.
