High-spin states in the 96Tc{^{96}Tc} nucleus

High-spin states in the $^{96}$Tc nucleus have been studied with the reactions $^{82}$Se($^{19}$F,5n$\gamma$) at 68 MeV and Zn($^{36}$S,$\alpha$p$x$n) at 130 MeV. Two $\gamma$-ray cascades (irregular bandlike structures) have been observed up to an excitation energy of about 10 MeV and spin 21-22$\hbar$

Band structures in doubly-odd 100^{100}Rh

High spin states of $^{100}$Rh have been populated using the reaction $^{70}$Zn+$^{36}$S at 130 MeV. $\gamma$-rays were detected with the EUROGAM2 array. The level structure of $^{100}$Rh has been extended up to 14.41 MeV excitation energy. Several band structures are observed. A band based on a I$^{\pi}$=8$^-$ state is developed up to the I$^{\pi}$=24$^-$ level. It is assigned as the $\pi$ $g_{9/2}^{-5}$ $\nu$ $h_{11/2}$ configuration

Level structure of

The decay of 123Ba to 123Cs has been studied with mass-separated sources. Singles spectra of γ-rays, X-rays and conversion electrons as well as γ - γ - t, γ - e − - t, and X - e − - t coincidences were recorded. A level scheme of 123Cs has been constructed including 26 new excited states and 82 transitions. The existence of a I π = 11/2−, T 1/2 = 1.7 s isomer, bandhead of the h 11/2 band, is confirmed. Its excitation energy equals 156.3 keV. A new T 1/2 = 114 ns isomer has been established at 232 keV using the in-beam recoil catcher technique. It is assigned to the I π = 9/2+ bandhead of the gpg 9/2 band. Collective bands based on the 1/2+ ground state and first 3/2+ excited state are proposed. The level structure is described in the frame of the interacting boson-fermion and core-quasiparticle coupling models

Low-spin excitations in

The low-spin excitations of the nucleus 146Sm which is just two neutrons and two protons away from the N = 82 shell and Z = 64 subshell closures have been investigated by means of the 143Nd (α, n) and 144Nd (α, 2n) fusion-evaporation reactions. We established 47 hitherto unknown energy levels up to 4.7MeV and 75 new transitions. In addition, 7 spin assignments were possible from the γ-γ angular correlation analysis. The structure of the possible candidates for a 2+ ⊗ 3− quadrupole-octupole multiplet are first discussed in terms of the harmonic vibrational model. A comparison of these states with the corresponding ones in the neighboring N = 84 isotones is also presented. Finally, the structure of the 146Sm nucleus is interpreted in terms of the IBA-spdf model. It is shown that the model is able to reproduce the experimental relative transition strengths of the 2+ ⊗ 3− quadrupole-octupole multiplet and also a series of collective properties such as the proposed double-octupole excitations
