[en] The value of nuclear level lifetimes is clear. Among several lifetime determination methods, the DSAM is the most generally used to extract lifetimes in the 10^-15-10^-12 s range, but it has been observed that stopping theory often fails at low recoil energies - i.e., for heavy nuclei. The author presents evidence that inelastic neutron scattering (INS) combined with DSAM can be used to extract level lifetimes in heavy nuclei. The method is capable of accessing low-spin excitations in stable nuclei and provides lifetimes when the γ-ray energy shift is about one keV or more. Details of the experimental method and of the lifetime extraction procedure, with special emphasis on the differences between INS-DSAM and other DSAM, are included. Good agreement is observed between these results and those from other lifetime determination methods which do not suffer from an incomplete knowledge of the stopping processes
