The present report gives a detailed analysis of experimental works and a review of alpha‐induced reaction cross‐section data of five alpha‐alpha nuclei, Mg‐24, Si‐28, S‐32, Ar‐36 and Ca‐40, for incident alpha energy up to 20 MeV. Alpha‐induced reactions play an important role in the helium burning stage of stars, novae, and supernovae. These reactions are basic to the CNO and Al‐Mg cycles, and also to the production of neutrons producing S and R processes occurring in stars. Thus, the availability of cross‐section data for these reactions is a prime need for the study of nuclear interactions taking place in stars.These data have been compiled as part of an international collaboration, funded in part by the Civilian Research & Development Foundation, and are available in the EXFOR databases. |
