RIKEN has provided fast radioactive isotope (RI) beams since 1990. The new facility of RIKEN RIBF (RI Beam Factory) started operation in the end of 2006, and various experimental studies using its high-intensity RI beams with energies around 200 MeV/nucleon have been performed. They include production of many new neutron-rich isotopes, lifetime measurements for several r-process nuclei, and...

Neutron-rich nuclei with magic numbers of neutrons and protons are reference points to map and understand the reorganization of the shell structure away from the line of beta stability. The region of nuclei near $^{78}$Ni, the doubly-magic nucleus with the largest N/Z ratio, is the focus of considerable experimental and theoretical interest. The extent of the magicity of $^{78}$Ni is still...

The region around the nucleus 68Ni, with a shell closure at Z = 28 and a sub-shell closure at N = 40, has drawn considerable interest over the past decades. 68Ni has properties that are typical of a doubly-magic nucleus, such as a high excitation energy and low B(E2:2+-0+) transition probability for the first excited 2+ level [1-3] and a 0+ level as the first excited state [4]. However, it...

Nuclear magnetic moments are sensitive probes of the single particle properties of the nuclear wave function. The magnetic moment operator, with its explicit dependence on protons or neutrons involved in the configuration of the state and on their angular momenta, serves as a stringent test of the proposed main configuration of the nuclear state, as well as of other admixtures. It is,...

The microscopic details concerning the assumed magicity of the 68Ni nucleus are not yet fully understood. Due to the parity change between fp orbitals and the g9/2 orbital, a small gap between these can lead to a high-lying first excited state in 68Ni. This underlying subshell structure seems also responsible for the unusual behavior of excited 0+ states in neighboring even-even nuclei.

The Beta decay of 82Zn has been studied at ISOLDE, CERN using a fast timing experimental
setup, which included a thin NE111A plastic beta detector, two HPGe gamma detectors and two
LaBr3(Ce) detectors all positioned in a close geometry. A new value for the lifetime of the beta
decaying g.s. of 82Zn was obtained and the -n branching ratio was measured for the first time.
Tentative level...
