TL;DR: The Rare Isotopes Investigation at GSI project combines the former EUROBALL Ge-Cluster detectors, the MINIBALL Ge detectors, BaF2--HECTOR detectors, and the fragment separator at the GSI for high-resolution in-beam gamma-ray spectroscopy measurements with radioactive beams.
Abstract: The Rare ISotopes INvestigation at GSI project combines the former EUROBALL Ge-Cluster detectors, the MINIBALL Ge detectors, BaF2--HECTOR detectors, and the fragment separator at GSI for high-resolution in-beam gamma-ray spectroscopy measurements with radioactive beams. These secondary beams produced at relativistic energies are used for Coulomb excitation or secondary fragmentation experiments in order to explore the nuclear structure of the projectiles or projectile like nuclei by measuring de-excitation photons. The newly designed detector array is described and the performance characteristics are given. Moreover, particularities of the experimental technique are discussed.

TL;DR: The gamma decay of the nuclei Ba-124,Ba-125 has been investigated by means of the EUROBALL spectrometer, coupled to the DIAMANT array of charged-particle detectors, using the reaction Ni-64 + Ni64 as discussed by the authors.

TL;DR: In this paper, the validity of the K-quantum number in the excited rapidly rotating 163Er nucleus was investigated by analyzing the variance and covariance of the spectrum fluctuations of γ-cascades feeding into low-K and high-K bands.

TL;DR: In this article, the γ decay of 124,125 Ba has been investigated with the EUROBALL array, using the reaction 64 Ni+ 64 Ni at Ebeam = 255 and 261 MeV.
Abstract: The γ decay of the nuclei 124,125 Ba has been investigated with the EUROBALL array, using the reaction 64 Ni+ 64 Ni at Ebeam = 255 and 261 MeV. Six new E1 transitions have been found in the nucleus 125 Ba, suggesting a significant role of octupole correlations in the origin of its parity doublets. The J π = 3 − level

TL;DR: In this paper, the γ -decay of the GDR in the 132 Ce compound nuclei produced by the reaction 64 Ni+ 68 Zn at Ebeam = 300 MeV, 400 MEV, 500 MeV (E ∗ of 100 MeV.
Abstract: The γ -decay of the GDR in the 132 Ce compound nuclei produced by the reaction 64 Ni+ 68 Zn at Ebeam = 300 MeV, 400 MeV, 500 MeV (E ∗ of 100 MeV, 150 MeV and 200 MeV) has been measured. We have detected heavy recoil nuclei, light charged particles and γ -rays. The data obtained with the symmetric reaction 64 Ni+ 68 Zn indicate emission from a fully equilibrated compound nucleus as deduced from the analysis of charged particle spectra. The GDR parameters are found to be consistent with the predictions of the thermal fluctuation model. (Some figures in this article are in colour only in the electronic version)
