The discrepancy between calculated and observed abundances of rare isotopes such as 36S and 46Ca is a longstanding problem. One of the reasons for this discrepancy was the lack or even the complete absence of experimental data on (n,p)- and (n,alpha)-reactions occurring during the nucleosynthesis process. This paper reports on an experimental programme set up to investigate (n,p)- and (n,alpha)-reactions and to determine their cross-sections for neutron energies from thermal up to about 500 keV. The measurements with thermal neutrons were performed at the high flux reactor of the ILL (Grenoble, France).
