[en] The ¹⁰⁴Cd, ¹⁰⁵Cd nuclei have been investigated in the ¹⁰²Pd(α,nγ)¹⁰⁴Cd, ¹⁰²Pd(α,nγ)¹⁰⁵Cd and ¹⁰²Pd(α,3nγ)¹⁰⁵Cd reactions. The proposed level schemes including states up to 4817.7 keV and 3342.9 keV for ¹⁰⁴Cd and ¹⁰⁵Cd respectively are based on results obtained from direct and delayed γ-ray spectra, excitation functions, γ-γ coincidences and γ-ray angular distributions. Intense E2 cascades have been observed in ¹⁰⁴Cd nucleus. Decoupled bands built on the νhsub(11/2) and on νgsub(7/2) are populated in ¹⁰⁵Cd

[en] Excited states of ¹⁰³Cd were populated by the ⁹⁴Mo(¹²C,3n)¹⁰³Cd reaction at 54 MeV. The dominant feature of the level scheme is the occurrence of a cascade of strong stretched E2 transitions based on the 7/2⁺ first excited state. Spins and parities are proposed, and the strengths of the gamma transitions are indicated. The quasi particle + rotor model reproduced the experimental data well. 2 figures

The proposed level schemes including states up to 4817.7 keV and 3342.9 keV for ¹⁰⁴Cd and ¹⁰⁵Cd respectively are based on results obtained from direct and delayed γ-ray spectra, excitation functions γ-γ coincidences and γ-ray angular distributions. Intense E2 cascades have been observed in the nucleus ¹⁰⁴Cd. Decoupled bands built on the νhsub(11/2)nd on νgsub(7/2) are populated in ¹⁰⁵Cd. (author)

[en] After a brief sketch of on-line beta-gamma spectrometry apparatus and results obtained in the period 1977-1979, data are presented on the systematics of energy levels in the odd Ir nuclei. 5 figures

[en] Levels of ¹⁰⁶Cd, populated by ¹⁰⁴Pd(α, 2nγ)¹⁰⁶Cd have been studied measuring direct and delayed γ-ray spectra, γ-γ coincidences and γ-ray angular distributions. A decay level scheme is proposed including states up tp 4,659.8 keV. Intense E2 transition cascades have been observed. The half-life of an isomeric level located at 4,659.8 keV has been measured: Tsub(1/2) = 62 +- 6 ns. (orig.)

[en] A considerable amount of experimental works has been recently done on the light Cadmium isotopes. The main purpose of these studies was to search for Coriolis decoupling mechanism in a transitional region. Negative and positive parity bands occuring in ¹⁰⁵Cd, ¹⁰⁷Cd, ¹⁰⁹Cd, ¹¹¹Cd have been correctly reproduced within the rotor-plus-particle model using self-consistent prolate core single-particle states. The aim of the present work is using HI reactions, to search for the high spin states in ¹⁰³Cd where only two low-lying levels are known so far, from on-line radioactivity studies, and to check whether this theoretical description remains still satisfactory

[en] The ¹⁰⁸Cd and ¹⁰⁶Cd isotopes have been studied from the β⁺/EC decay of sup(108m+g)In and sup(106m+g)In, with the ISOCELE facility. Gamma-ray, conversion electron γ-γ-t and e^--γ-t coincidence measurements have been performed and level schemes of ¹⁰⁸Cd and ¹⁰⁶Cd have been built. A O⁺ excited state has been clearly established at 1913.2 keV in ¹⁰⁸Cd. The properties of the excited states are discussed in terms of vibrator + particle approach and interacting boson approximation. The present results lead us to assign the spin and parity value Isup(π) = 7⁺ for the isomeric state in ¹⁰⁸In and ¹⁰⁶In, this is discussed in the framework of the j-j coupling model

[en] Level properties of ¹⁸⁵Ir were investigated by in-beam γ-spectroscopy using (α,4n) and (α,6n) reactions with Esub(α) ranging from 41 to 77 MeV. A well-developed system of levels built on the hsub(9/2) subshell is excited. A band built on the 11/2^- isomeric state is also observed. In distinction from heavier Ir isotopes, only a single positive parity band is developed to high-spin states. Two isomers with Tsub(1/2)=120 ns and 40 ns are found for excitation energies above 22 MeV. The experimental results are discussed in terms of rotational models including the Coriolis coupling and providing for a stable triaxial shape of the ¹⁸⁵Ir nucleus. (Auth.)

[en] Gamma and conversion electron lines following the β-decay of ^118120122Cs nuclei have been investigated at the ISOLDE facility. Evidence has been found for two isomeric states with similar half-lives in ¹¹⁸¹²⁰Cs. Level schemes of ^118120122Xe including levels of the quasi-ground state, gamma and beta bands have been established. The structure of these nuclei is discussed in the framework of the rotational model and the vibrational limit of the interacting boson approximation (IBA) approach. (Auth.)
