]The activities of 18 radionuclides in 4 samples from the Saint-Séverin meteorite have been measured after chemical separation. The results show that the DI sample from the D piece has been less irradiated than the samples B 2 , B 3 and B 4 from the B piece. This is based on activities of isotopes produced both by spallation as 26 Al, 53 Mn, 54 Mn, 55 Fe, 57 Co and by thermal neutron capture as 59 Ni and 60 Co. Comparison of experimental values to calculated production rates suggests that the D piece was connected to the main body of the meteorite by a small surface, and that the DI sample in this piece was opposite to the main body of the meteorite.
