摘要：

Mean lives of several excited nuclear states have been determined using the Moessbauer effect. The mean life is deduced by interpolating the experimental line width to zero effective thickness of the resonance absorber. An improved expression is used for the interpolation. The results are: τ(140 keV level of99Tc)=277(14)ps τ(136 keV level of181Ta)=55 (3)ps τ(129 keV level of191Ir)=129 (2)ps τ(139 keV level of193Ir)=115 (3)ps τ(77 keV level of197Au)=2.73 (2)ns. © 1969 Springer-Verlag.
