A new extractant, [N,N-di（2-ethylhexyl）aminolmethylphenylphosphinic acid （DEAPP）, was synthesized to de- velop the mutual separation techniques of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ）. the extraction selectivity for In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP was higher than that of the commercial phosphorus acid extractants such as D2EHPA and PC-88A. the extraction selectivity for metal ions in 1 mob L 1 aqueous ammonium nitrate solution with DEAPP was in the following order： In（Ⅲ）〉 Ga（Ⅲ）〉 Zn（Ⅱ）. these selective extraction behaviors indicate that the amino moiety of DEAPP plays an important role in the mutual separation of ln（Ⅲ）, Ga（Ⅲ） and Zn（ll）. the extraction equilibria of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP （ = HR） were expressed by the following reactions： In3＋＋ 2（HR）2 InR3（HR）＋ 3H＋, Ga3＋＋ 1.5（HR）2 ＋ N- = GaR2（HR）（NO3）＋ 2H＋, and Zn2＋ 4- 2（HR）2 ZnR2 （HR） 2 determined 4- 2H＋. the extraction equilibrium constants of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP were to be Kex, M = 1.7 × 104 [*** 1], 4.17 [（***-1）s], and 1.55 × 10 2 [-], respectively.

A new rotational band has been identified and assigned to 188Au for the first time using the 173Yb(19F,4nγ) reaction at the beam energies of 86 and 90 MeV. this band is proposed to be built on the πh9/2  νi13/2 configuration by comparing the band properties with known bands in neighboring nuclei. the prolate-to-oblate shape transition through triaxial shape has been proposed to occur around 188Au for the πh9/2  νi13/2 bands in odd-odd Au isotopes on the basis of total Routhian surface (tRS) calculations.

High-spin states in 145tb have been populated using the 118Sn (32S, 1p4n) reaction at beam energy of 165 MeV. the level scheme of 145tb has been established up to Ex ≈7.4 MeV. the level scheme shows characteristics of a spherical or slightly oblate nucleus. Based on the systematic trends of the level structure in the neighboring N = 80 isotones, the level structure in 145tb below 2 MeV excitation is well explained by coupling an h11/2valence proton to the even-even 144Gd core. Above 2 MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.

the level structure of ^19Opt has been studied experimentally using the ^176yb （^18O, 4n） reaction at beam energies of 88 and 95 MeV. γ-γ-t coincidence measurements were carried out. Based on the analysis of t-t coincidence relationships, the level scheme of ^190Pt is extended to high-spin states. A new structure built on the 3413.6 keV 14＋ state has been observed, and the ＂vi13/2^-2 vh9/2^-1 vj （j = P3/2 or f5/2） configuration is tentatively assigned to it.

Excited states of125Sb have been studied using in-beam γ spectroscopy techniques via the124Sn(7Li, α2n) reaction at a beam energy of 32 MeV. A high-spin level scheme including 21 new γ-transitions and 14 new excited states have been established. three isomers have been identified at 1970, 2110 and 2471 keV and the ranges of their half-lives have been estimated from the delayed coincidence data. the level structure of125Sb is discussed in terms of particle-core excitation coupling. With the help of empirical shell model calculations the three isomers are proposed to have three-quasiparticle πg7/2?v(h 11/2 s 1/2)5?, πg7/2?v(h 11/2 d 3/2)7? and πg7/2?v(h 11 2/2 )10 + configurations, respectively.

A standard in-beam γ-spectroscopy experiment for 179Au has been performed via the 149Sm (35Cl, 5n) reaction at beam energies of 164–180MeV. Based on the analysis of the experimental results, a rotational band built on the 1/2[660](πi13/2) proton intruder orbital is established for 179Au for the first time. Systematic properties of the 1/2[660](i13/2) band in odd-A Au nuclei are discussed, and the evolution of bandhead energy and deformation with changing neutron number are revealed.

High-spin states in182Au have been produced and studied via the152Sm(35Cl,5nγ)182Au reaction. the level scheme consisting of the πh 9/2?νi 13/2 and πi 13/2?νi 13/2 bands has been established for the first time. the low spin signature inversion in both bands has been found. the observed signature inversion phenomena can be interpreted qualitatively using the pairing and deformation self-consistent cranked Wood-Saxon calculations.
