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…
Half-lives and branchings for β-delayed neutron emission for neutron-rich Co-Cu isotopes in the r-process
P. Hosmer, H. Schatz, A. Aprahamian +23
The β decays of very neutron-rich nuclides in the Co-Zn region were studied experimentally at the National Superconducting Cyclotron Laboratory using the NSCL β-counting station in…
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…
Half Life of the Doubly-magic r-Process Nucleus 78Ni
P. T. Hosmer, H. Schatz, A. Aprahamian +19
Nuclei with magic numbers serve as important benchmarks in nuclear theory. In addition, neutron-rich nuclei play an important role in the astrophysical rapid neutron-capture proces…
A tentative 4- isomeric state in Sr-98
B. Pfeiffer, G. Lhersonneau, H. Gabelmann +2
Annual Report 2001, Institut fuer Kernchemie, Johannes-Gutenberg-Universitaet, Mainz, Germany
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…
