    First results from laser spectroscopy on bunched radioactive beams from the JYFL ion-beam cooler

    A new RFQ ion-beam cooler and buncher, installed after the mass-separating magnet of the ion guide isotope separator, IGISOL, JYFL, has dramatically increased the scope of on-line laser spectroscopy at this fa...

    Ion beam cooler-buncher at the IGISOL facility

    An ion beam cooler-buncher for manipulating low-energy radioactive ion beams at the IGISOL facility is described. The cooler-buncher serves as a source of cooled ion bunches for collinear laser spectroscopy an...

    Studying exotic nuclides close to the N = Z line at the HIGISOL facility

    The ion guide [1, 2] for heavy-ion fusion-evaporation reactions (HIGISOL) which was developed by Béraud et al. [3] has been implemented at the IGISOL facility in Jyväskylä [4]. This system was modified over th...

    Beta decay of 57Zn*

    Beta-delayed proton decay of 57Zn has been investigated at the GSI on-line isotope separator. The studied 57Zn nuclei were produced in fusion evaporation reactions by using a 150 MeV 32S beam on a 28Si target. Be...

    Isomeric state of 80Y and its role in the astrophysical rp-process

    A careful investigation of the isomeric transition of the long-lived state at 228.5 keV excitation energy in 80Y has been done. The HIGISOL facility at the Jyväskylä isochronous cyclotron has been used. We used t...

    Ground-state spin of 59Mn

    Beta-decay of 59Mn has been studied at PSB-ISOLDE, CERN. The intense and pure Mn beam was produced using the Resonance Ionization Laser Ion Source (RILIS). Based on the measured β-decay rates the ground-state spi...

    Production of neutron-rich isotopes in fission of uranium induced by neutrons of 20 MeV average energy

    In the context of a parameter study conducted by several laboratories for future European radioactive beam facilities based on fast-neutron induced fission, in particular for the SPIRAL-II project at GANIL, we...

    Beta decay of neutron-rich 118Rh and the lowest excited states in 118Pd

    Beta decay of a refractory isotope 118Rh produced in symmetric fission and mass separated by the ion guide technique has been applied for the study of low-lying excited states of 118Pd. The yrast band in 118Pd ...

    The decay of the neutron–rich nucleus 216Bi

    The decay of the neutron–rich isotope 216Bi, produced by proton–induced spallation at the PS Booster–ISOLDE facility, was investigated by β-γγ, αγ coincidence and spectrum-multiscaling measurements. A new method...

    A new isomer in 125La

    Levels in 125La have been studied via β+/EC decay of on-line mass-separated 125Ce using the HIGISOL technique. A new (390 ± 40) ms isomer is definitely attributed to 125La by conversion electron measurements of ...
