Abstract
Excited states in 136Ba, populated in deep inelastic collisions by the interaction of 450 MeV 82Se ions with a 139La target, have been studied by means of in-beam 
-ray spectroscopy. A new isomer with 
has been identified at an excitation energy E
x
= 3.357 MeV. The half-life was determined as 
ns. The extracted B(E2) value is much smaller than those in 132Te and 134Xe. This hindrance is investigated by a shell model calculation.
