High-spin {mu}s isomer in {sup 98}Zr
G. S. Simpson,J. A. Pinston,D. L. Balabanski,J. Genevey,Georgi P. Georgiev,J. Jolie,D. S. Judson,R. Orlandi,A. Scherillo,I. Tsekhanovich,W. Urban,N. Warr +11 more
TL;DR: A high-spin isomer was observed using the Lohengrin mass spectrometer of the high-flux reactor of the Institut Laue-Langevin, Grenoble.
New information on medium-spin structure of {sup 133}Sb
TL;DR: In this article, a new 4191.8 keV level in the nucleus of the 14.6 \ensuremath{\mu}s isomer was observed, interpreted as the 11/2}^{+}$ member of the $1.7/2 \enuremath{bigotimes}\mathrm{core} configuration, predicted by the shell model at 4095 keV.

T. Rząca-Urban,K. Pągowska,W. Urban,A. Złomaniec,J. Genevey,J. A. Pinston,G. S. Simpson,M. Saha Sarkar,S. Sarkar,H. Faust,A. Scherillo,I. Tsekhanovich,R. Orlandi,John Durell,A. G. Smith,I. Ahmand +15 more
TL;DR: In this paper, the I-138 nucleus was populated in the spontaneous fission of Cm-248 and studied by means of prompt gamma-ray spectroscopy using the EUROGAM 2 array, including T-1/2=1.3 mu s isomer decaying by a stretched E2 transition of 68 keV.

TL;DR: A combination of germanium detectors has been installed at the PF1B neutron guide of the ILL to perform the prompt spectroscopy of neutron-rich nuclei produced in the neutron-capture induced-fission of 235 U and 241 Pu.

TL;DR: In this article, the authors present a new setup called FIPPS (FIssion Product Prompt Spectroscopy), which combines a collimated neutron beam, a highly efficient cluster of Ge detectors, a gas filled magnet and auxiliary detectors.
