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- yrast

The N=82 136Ba nucleus has a proton number between the Z=50 and Z=64 shell closures. Thus it is interesting to obtain detailed spectroscopic information on low-lying states in 136Ba. Such experimental information is i... 详细信息

The level structure of doubly odd nucleus 146Tb has been studied via the 118Sn(32S, 1p 3n)146Tb reaction by using techniques of in-beam γ-iay spectroscopy. measurements of 7-ray excitation functions, 7-ray anisotropies, X-γ and γ-γ-t coincidences were performed with 12 BGO(AC)HPGe detectors. Based on the γ-γ coincidence relationships, intensity balances and cross-over transitions, the level scheme of 146Tb has been extended up to

Here, t refers to therelative time difference between any two coincident γ-rays detected within ±200 ns. A level scheme of 145Tb,including 81 γ-transitions as shown in Fig.1, has been established up to 7.4 meV in excitation energy and spin-

High-spin states of odd-odd 172Re has been studied, for the first time, by using 149Sm(27Al, 4n) 172Re reaction. The 27A1 beam was provided by the JAERI (Japan Atomic Energy Research Institute) tandem accelerator. The target was an enriched 149Sm metallic powder of 2.1 mg/cm2 thickness evaporated on to a 5.5 mg/cm2 Pb backing layer. A γ-ray detector array was used comprising 12 HPGe's with BGO anti-Compton
