The experiment was performed at the tandem accelerator laboratory in the University of Tsukuba, Japan. The target is an isotopically enriched ^128Te metallic foil of 2.3mg/cm^2 thickness with a 3mg/cm^2 gold backing. Nine anti-Compton HPGe detectors were employed for the measurements of γ-γ-t coincidences. The level scheme of ^134Ba, deduced from this study, was shown in Fig.1.展开更多
High spin states of ^135La have been experimentally studied by ^128Te(^10B, 3n)^135La reaction. The ^10B beam was provided by the tandem accelerator laboratory in the University of Tsukuba, Japan.

The ^10B beam was provided by the tandem accelerator laboratory in the University of Tsukuba, Japan. Based on the γ-γ coincidence relationships, relative intensities and ADO ratios, a level scheme of ^135La has been established.展开更多
