摘要：

The nucleus Ba-135 has been studied via primary, secondary gamma-rays, gammagamma coincidences following thermal-neutron capture. A level scheme was established up to 3.7 MeV consisting of 41 levels including 114 gamma-transitions. The neutron binding energy was determined to be 6971.78 (17) keV. The total thermal cross section and isomer production of the 11-/2 state were determined to be sigma(tot) = 1.4(4) and sigma(Ba-135) = 0.11(2) barn. The level energies, E2 and M1 transitions and electromagnetic moments were compared with model predictions of the interacting boson-fermion model (IBFM).
