High-spin states in doubly odd ^170Re nucleus have been investigated for the first time, through in-beam γ-ray spectroscopy, following the ^142Nd(^32S, 1p3n γ) ^170Re reaction at 166 McV bombarding energy. The ^32 Sbeam was provided by the tandem accelerator at the China Institute of Atomic Energy, Bcijing. The ^142 Ndtarget is an enriched metallic foil of about 2.2 mg/cm^2 thickness with a 7.0 mg/cm^2 Pb backing to stop the recoiling nuclei. Measurement of X-γ, and γ-γ coincidences wcrc performed with 12 BGO(AC)HPGc detectors. A total of 150 million coincidence events wcrc recorded. The detector energies and cfficicncics wcrc

The high-spin states of very neutron-deficient doubly odd nucleus ^190T1 have been investigated via the ^160Gd(^35C1, 5n)^190T1 reaction by using techniques of in-beam γ-ray spectroscopy. Measurements of X-γ and γ-γ-t coincidences were performed with 12BGO(AC)HPGe detectors. Based on the gated spectra, γ-γ coinci-dence relationships, γ ray energy sums, γ ray relative intensities and the previous work, the level

Excited states of ^134Ba, populated via the heavy-ion induced ^128Te(^10B, 1p3n)134Ba reaction at 46 MeV beam energy, have been studied to medium and high spins by in-beam γ-ray spectroscopy techniques. 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.

We established the level scheme of 145Tb for the first time. The excited states below 2 MeV have been interpreted qualitatively by coupling an h11/2 valence proton to the 0+, 2+, 4+ and 3- excited states in the 144Gd core nucleus, and the yrast levels in excitation energy range from 2.1 to 3.4 MeV have been suggested from the (πh211/2d-15/2/g-17/2) proton excitations or the couplings of the h11/2 proton to the 5- and 7-
