Abstract

We have investigated and analyzed the experimental data of the odd A nuclear IT (isomeric transiton) decay around Pb.We find a simple law for the IT decay halflives of the odd A nuclear isomer: there is a parabolic law between the logarithm of the halflives of the isomer with the same angular momentum and parity along the isotopic chain.This shows there is an exponential law between the halflives of IT decay and the mass number A. The analysis of the multipolarity of the IT decay could make us have a clear recognition for the physical properties.We have also discussed the possible physics behind this simple law.
