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.
Journal ArticleDOI
Proton–neutron structure of the N=52 nucleus 92Zr
V. Werner,D. Belic,P. von Brentano,C. Fransen,C. Fransen,Alexandra Gade,H. von Garrel,J. Jolie,U. Kneissl,Christoph Kohstall,A. Linnemann,A. F. Lisetskiy,Norbert Pietralla,H. H. Pitz,Marcus Scheck,K.-H. Speidel,F. Stedile,S. W. Yates +17 more
TL;DR: In this paper, the authors performed a photon scattering experiment on the N=52 isotone 92Zr and showed that both, single particle and collective degrees of freedom are present in the low-lying levels of 92 Zr.
Journal ArticleDOI
Evidence for Proton Excitations in 130,132,134,136 Xe Isotopes from Measurements of g Factors of 2 + 1 and 4 + 1 States

TL;DR: In this paper, a steady decrease in the number of neutron holes increases in the lighter nuclei below the closed $N=82$ neutron shell, a characteristic of proton excitation.
Journal ArticleDOI
