Abstract
Two low-lying isomeric states in 169Ta have been
identified via 159Tb(16O,6n)169Ta reaction. Their
half-lives are measured to be
ns for the 9/2- level and
ns for the 5/2- level by using the delayed
-
coincidence method. These two isomeric states are considered to be the
bandheads with 9/2-[514] and 1/2-[541] configurations
respectively.
