The cross section of the 33S(n,α)30Si reaction was measured in a neutron energy spectrum yielding the stellar rate for a thermal energy of kT=25 keV. For the 36Cl(n,p)36S reaction, the experiment was performed in the neutron energy range from 10 to 260 keV. Our new result for 33S resolves the problem of a large discrepancy between two previous experiments. In case of 36Cl it could be shown that the (n,α) channel is negligibly small compared to the (n,p) reaction at s-process conditions. The present results are used for a detailed discussion of a possble s-process origin of the rare neutron-rich isotope 36S.
