    Measurement ofg-factors in160Yb by aγ-γ coincidence technique

    Aγ-γ coincidence technique has been developed forg-factor measurements of short-lived nuclear states. The method involvesγ-detection in 4π geometry as well as transient magnetic fields and the recoil-distance tec...

    Radiative fusion induced by massive nuclei

    In bombardments of 90Zr, 92Zr and 94Mo with 90Zr ions at energies near the Coulomb barrier, radiative fusion has been observed where the compound nuclei do not evaporate nucleons but emit only γ radiation. The de...

    Low-frequency variability and predicted superluminal motion in 3C147

    VLBI observations of 3C147 reveal that its core is a low-frequency variable radio source which has brightened by a factor of 2 in 6 years. In combination with X-ray observations, this implies that bulk relativ...
