Neutrons produced close to the Ge detectors of SPI can induce nuclear reactions, leading to the delayed emission of gamma -rays contributing to the background in the gamma -ray lines of astrophysical interest. The cross sections for such neutron-induced reactions were measured at Louvain-la-Neuve. This contribution report on last experiments dealing with the 122-136 keV gamma -rays from /sup 57/Co and the 1173-1332 keV gamma -rays from /sup 60/Fe.
