    A universal stopped and low-energy RI-beam facility (SLOWRI) [1] is finally being installed at RIKEN RIBF. It will convert relativistic RI-beams from the inflight separator BigRIPS to low-energy, low-emittance, high-purity RI beams using two different gas catcher cells: RF-carpet gas cell and PALIS gas cell [2, 3]. The former is a 1.5-m long cell filled with 100 mbar He gas and operated at...

    Medical use of radioactive isotopes for diagnosis and therapy is a widespread and commonly accepted application of radioactivity. It has historical roots back to Curie, Hevesy and Lawrence, and while the principles are the same as a 100 years ago, the number of applications, their sophistication and precision, and not least the clinical benefits are growing each day. Although “new”...

    The beta-decay of the proton rich nuclei $^{21}$Mg was used as a calibration source for the IS507 experiment. The aim of the experiment was to study the beta-decay of $^{20}$Mg with a dedicated charged particle detection setup consisting of two opposing $\Delta$E-E telescopes. As $^{21}$Mg is close in mass to $^{20}$Mg and is a known beta-delayed proton emitter, with intense proton branches,...

    The region surrounding the neutron number N = 60 for the Sr and Zr isotopic chains is an interesting example of shape evolution. Starting from the N = 50 closed spherical shell, and removing a few neutrons, the Sr and Zr isotopes become well deformed. On the neutron-rich side of these isotopic chains, N = 56 is observed to become an effective sub-shell closure with $^{96}$Zr exhibiting the...

    The neutron-rich A=100 mass region has recently risen up a high interest of the nuclear structure community. When going from N=58 to N=60, a rapid shape transition occurs from spherical to well deformed ground state shape, similar to what is observed in the rare earths region. This region firstly accessible by fission [1] has been later studied by mass and laser spectroscopy (e.g. [2]), which...

    Beta-decay spectroscopy is one of the most important tools for the study of nuclear structure. In exotic nuclei beta-decay can often be followed by the emission of delayed particles, a process which becomes the dominant decay channel when approaching the driplines. In the most exotic species, the emission of two or more delayed particles can also occur with a significant...

    The TWINEBIS is a replica of REXEBIS used for off-line research and development. REXEBIS is designed to provide a stable 500 mA electron beam at an electron energy of approximately 6.5 keV. During long term operation the REXEBIS is typically run only at 200 mA for reliability purposes. The full design value operation was never used in practice. Recently the first 500 mA electron beam was...

    ISOLTRAP is a state-of-the-art experiment at ISOLDE-CERN for Penning-trap mass spectrometry of short-lived nuclides [1, 2]. The Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) [3] technique, recently developed by SHIPTRAP at GSI, is a promising approach to gain precision and mass resolving power for Penning-trap spectrometers. Its use would lead to an enhancement in precision of a factor of 5...

    Manganites and their exquisite electronic properties have been extensively studied in the last decade due to both fundamental interest and possible applications of colossal magnetoresistance, magnetocaloric and multiferroicc properties [1,2]. Additionally, low-cost AMnO3 and doped manganites have shown promising results for catalysts solutions [3,4]. In these systems orbital...

    SiC is a wide band gap semiconductor with an increasing number of applications in high-temperature electronics. Similar to Si, transition metals (TMs) in SiC are the source of deep levels in the band gap, however, the knowledge on structural properties of TMs in SiC, such as possible lattice sites, is much less advanced. In this work we report first results on the lattice site location of...

    As excitation energy increases towards the particle separation energy, the level density increases rapidly, creating the quasi-continuum. Nuclear properties in this excitation energy region are best characterized using statistical quantities, such as the photon strength function (PSF) which is the ability of atomic nuclei to emit and absorb photons. For several Fe isotopes an unexpected...

    The ternary alloy systems based on AlN, GaN and InN are widely used in LEDs. The advantage is the continuous change in the bandgap that can be tailored by the alloy composition. Interestingly, the dependence of the bandgap on the constituents is not following Vegard's law which states that the lattice constants should change linear with the alloy content. But measurements show, that an...

    Measuring the proton emission decay widths and corroborating them with microscopic calculations have yielded rich information about the structure and decay properties of proton drip nuclei. The spectroscopic data on the low lying states of these nuclei are also crucial in complementing the information from decay widths. Apart from proton emitters, the spectroscopic data of low lying states...

    T-REX is a large acceptance silicon array which is coupled to MINIBALL at ISOLDE. Its main purpose it to measure angular distributions of emitted light particles after transfer reactions, allowing to quantify the shell model configurations of excited single particle states or collective excitations in exotic nuclei. Recently, T-REX was re-designed to also allow for Coulomb-Excitation...

    The higher beam energy, and improved beam qualities, that HIE-ISOLDE will offer opens the door to new possibilities for nuclear reaction studies at the facility. Simulation results for a mass separator device and a ray-tracing spectrometer for secondary reactions with post-accelerated beams will be presented. Realistic HIE-ISOLDE parameters are used as input to the simulations and a variety of...

    The region around the nucleus 68Ni, with a shell closure at Z = 28 and a sub-shell closure at N = 40, is the source of considerable interest in nuclear-structure studies. Despite a significant set of experimental and theoretical information available on 68Ni [1-5], the origin of its structure is still being questioned. A recent clarification of the energy and spin assignment of several...

    I will present on development of a diagnostic system for the HIE-ISOLDE accelerating cavity. The HIE-ISOLDE cavity is a superconducting quater-wave resonator made of a copper substrate on which a niobium film of a few micron is sputtered. Five cavities have been constructed for the first cryomodule by last November; however their performance is not always as good as a nominal value (Q-value...
