Abstract
The band structures built on the 5- isomeric state
(
T1/2=3.46 m) in the doubly odd 130Cs nucleus have been
established up to via the
124Sn(11B, 5n)130Cs reaction. The previously observed
bands based on the
,
and
configurations and a positive-parity side band with
multiple connections to the
signature partner of the yrast
band have been extended to
higher spins. A new band based on the
configuration is observed. The yrast
band exhibits anomalous
signature splitting whose magnitude decreases up to spin 15 and then
increases without restoring the normal signature splitting.
