Isospin breaking in the $^{71}$Kr and $^{71}$Br mirror system Open
Isospin symmetry is a fundamental concept in nuclear physics. Even though isospin symmetry is partially broken, it holds approximately for most nuclear systems, which makes exceptions very interesting from the nuclear structure perspective…

The β-decay of <sup>71</sup>Kr: Precise measurement of the half-life Open
The very proton-rich 71 Kr isotope was produced through the in-flight fragmentation of 78 Kr on a beryllium target at RIKEN – Nishina Center in order to study its β-decay properties. A stack of double-sided silicon strip detectors, called …

Charge-changing cross sections for $^{42\textrm{--}51}$Ca and effect of charged-particle evaporation induced by neutron removal reaction Open
Charge-changing cross sections $σ_\mathrm{CC}$ for $^{42\textrm{--}51}$Ca on a carbon target at around 280~MeV/nucleon have been measured. The measured $σ_\mathrm{CC}$ values differ significantly from the previously developed calculations …
Experimental studies of the two-step scheme with an intense radioactive beam for next-generation production of very neutron-rich nuclei Open
The study of nuclei in the yet-unexplored, very neutron-rich, mid- to heavy-mass region of the nuclear chart, comprising perhaps half of all nuclei predicted to exist, is leading to new and/or upgraded facilities, as well as to research in…

Lifetime measurement of the <sup>26</sup>0 g.s. at SAMURAI Open
The ground state of the neutron unbound nucleus 26 O is speculated to have a lifetime in the pico-second regime. In order to determine the decay lifetime of the 26 O ground state with high sensitivity and precision, a new method has been a…

Experimental study of <sup>4</sup> n with <sup>8</sup>He(p,2p) reaction Open
The tetraneutron has attracted the attention of nuclear physicists during the past decades, but there is still no unambiguous confirmation of its existence or non-existence. A new experiment based on 8 He( p,2p ) 7 H{ t + 4 n } reaction, w…
The parity-transfer $({}^{16}{\rm O},{}^{16}{\rm F}(0^-,{\rm g.s.}))$ reaction as a probe of isovector $0^-$ states in nuclei Open
The parity-transfer $({}^{16}{\rm O},{}^{16}{\rm F}(0^-,{\rm g.s.}))$ reaction is presented as a new probe for investigating isovector $0^-$ states in nuclei. The properties of $0^-$ states provide a stringent test of the threshold density…
