    This work reports on the measurements performed during the commissioning of the GARIS-III separator in RIKEN with the study of the <sup>40</sup> Ar + <sup>208</sup> Pb → <sup>248</sup> Fm <sup>*</sup> reaction. The excitation functions of the 2n, 3n, and 4n exit channels were measured with maximum cross sections of 27.5 ± 6.4, 37.4 ± 6.2, and 2.45 ± 0.52 nb, respectively. The obtained results were also compared to previous measurements from GSI and GARIS-II, as well as to theoretical statistical models. The measurements were also used to fully characterize the GARIS-III separator regarding its transmission, implantation profile and detection efficiency of the focal plane detector system.

    We aim to develop a compact monoenergetic β -ray source that is capable of emitting electrons with a chosen energy and to assess its performance via Geant4 simulation. The proposed source consists of a <sup>90</sup> Sr source with neodymium permanent magnets, collimators, and iron yokes, and its output energy is tunable by changing a inter-magnet distance “gap”. Magnet sizes and the overall geometry were optimised using magnetic-field modelling with ANSYS Maxwell and particle-transport studies with the Geant4 toolkit. The simulations indicate that the electron energy can be set at a certain value between 0.5 MeV–2 MeV, with full width at half maximum of less than 250 keV.

    We report atomic mass measurements of the unstable nuclides <sup>73−75</sup> Ni, <sup>73−78</sup> Cu, and <sup>74−78</sup> Zn, which have been accomplished using multi-reflection time-of-flight mass spectrometry combined with new technical developments to resolve challenges for exotic-isotope identification and selection. The isotopes were produced in-flight at the RIKEN’s Radioactive Ion Beam Facility and delivered to the combined gas cell and multi-reflection system installed downstream of the ZeroDegree spectrometer. The incoming high-energy beam was energy-degraded and subsequently stopped in a helium gas cell. The energy degrader thickness was optimized using a new method that employs signals from plastic scintillators located upstream and downstream of the helium-filled gas cell. Extracted isotopes of interest were mass-selected by the in-MRTOF deflector method, for which we discuss simultaneous selection of multiple isobar chains. The ions of interest were identified unambiguously using β-decay-correlated mass measurements for the first time, which is demonstrated for <sup>78</sup> Zn. The new mass values are compared with literature values and recent measurements performed at JYFLTRAP and ISOLTRAP, where a generally good agreement is observed.

    Properties such as lifetimes and masses of neutron-rich nuclei are key parameters for elucidating the astrophysical rapid neutron capture process (r-process). Due to the lack of experimental nuclear data in the relevant extremely neutron-rich region, especially near and above N = 126, the predictions of theoretical nuclear models are crucial for simulating r-process nucleosynthesis. Experimental studies of the properties and structures of neutron-rich nuclei from near the β stability line up to the r-process path provide important inputs to these theoretical models, improving the accuracy of predictions for the nuclear properties involved in the rprocess. We are developing the KEK Isotope Separation System (KISS) at the RIKEN RIBF facility to produce and separate these nuclei to perform spectroscopy experiments. The nuclei of interest are produced by multinucleon transfer reactions, which have been recently attracting renewed interest as they provide a way to access neutron-rich nuclei that are difficult to produce by other methods such as complete fusion or fragmentation. We have performed nuclear and laser spectroscopy, lifetime and mass measurements of neutron-rich nuclei of refractory elements near the N = 126 region using <sup>198,nat</sup>Pt, <sup>nat</sup>Ta, <sup>nat</sup>W, and <sup>nat</sup>Ir targets irradiated with <sup>136</sup>Xe beams. We also extend our spectroscopic studies into the neutron-rich actinide region using <sup>238</sup>U beams. This paper introduces the KISS facility and provides an overview of the nuclear spectroscopy experiments carried out there. We also introduce the KISS-1.5 project, which was started in FY2024 to further extend the research into the neutron-rich region.

    The atomic masses of isotopes of elements beyond fermium, which can presently only be produced online via fusion-evaporation reactions, have until recently been determined only from α decay chains reaching nuclides with known atomic masses. Especially in the case of lower-yield nuclides, for which the sufficiently detailed nuclear spectroscopy required to fully determine the nuclear structure is not possible, such indirect mass determinations may suffer systematic errors. For many superheavy nuclides, their decay chains end in spontaneous fission or in β-decay prior to reaching nuclides of known mass. To address this dearth of accurate atomic masses, we have developed a multi-reflection time-of-flight mass spectrograph that can make use of decay-correlations to accurately and precisely determine atomic masses for the very low-yield superheavy nuclides.

    Abstract

    Previously, we developed an α-TOF detector for correlated measurements of atomic masses and decay properties of radioactive isotopes using a multi-reflection time-of-flight mass spectrograph, and successfully demonstrated α-decay-correlated mass measurements of heavy and superheavy nuclides. In this work, we develop a β-TOF detector, an improvement upon the α-TOF detector, to extend this technology to β-decaying nuclides. Online commissioning with 81Ga yielded a measured half-life of 1.44(31) s, in agreement with the previous literature, and confirmed the efficiency of detecting a decay-correlated event to be consistent with the solid angle limitation.
