Half-Lives of Low-Lying Isomeric States in ^(169)Ta

         

摘要

Two low-lying isomeric states in 169Ta have been identified via ^(159)Tb(l6O,6nγ)^(169)Ta reaction.Their half-lives are measured to be 28±5ns for the 9/2^(-)level and 17±4 ns for the 5/2^(-)level by using the delayedγ-γcoincidence method.These two isomeric states are considered to be the bandheads with 9/2-[514]and 1/2-[541]configurations,respectively.Possible neutron quasiparticle configuration for the ground state of ^(169)W is discussed.
