Beta-decay of nuclei around Se-90. Search for signatures of a N=56 sub-shell closure relevant the r-process

M. Quinn, A. Aprahamian, J. Pereira +26

Nuclear structure plays a significant role on the rapid neutron capture process (r-process) since shapes evolve with the emergence of shells and sub-shells. There was some indicati…

Beta-decay half-lives and beta-delayed neutron emission probabilities of nuclei in the region below A=110, relevant for the r-process

J. Pereira, S. Hennrich, A. Aprahamian +21

Measurements of the beta-decay properties of r-process nuclei below A=110 have been completed at the National Superconducting Cyclotron Laboratory, at Michigan State University. Be…

Beta decay studies of r-process nuclei at the National Superconducting Cyclotron Laboratory

J. Pereira, A. Aprahamian, O. Arndt +22

The impact of nuclear physics on astrophysical r-process models is discussed, emphasizing the importance of beta-decay properties of neutron-rich nuclei. Several r-process motivate…

First decay study of the very neutron-rich isotope Br-93

G. Lhersonneau, A. Woehr, B. Pfeiffer +2

The decay of the mass-separated, very neutron-rich isotope Br-93 has been studied by gamma-spectroscopy. A level scheme of its daughter Kr-93 has been constructed. Level energies,…

Identical transitions in the strongly deformed Sr-99 and Sr-100

G. Lhersonneau, B. Pfeiffer, H. Gabelmann +2

The decay of the very neutron-rich nucleus Rb-100 has been studied by gamma-spectroscopy of on-line mass-separated samples. Schemes for beta-decay to Sr-100 and beta-n-decay to Sr-…

Decay of neutron-rich Mn nuclides and deformation of heavy Fe isotopes

M. Hannawald, T. Kautzsch, A. Woehr +12

The use of chemically selective laser ionization combined with beta-delayed neutron counting at CERN/ISOLDE has permitted identification and half-life measurements for 623-ms Mn-61…
