    Heavy Elements — Experiments on Synthesis and Decay

    Attempts were made to identify new elements in heavy ion fusion reactions. After an effective separation by the velocity filter SHIP the ions passed a pair of thin secondary electron detectors and were finally...

    Evidence for nuclear shape coexistence in180Hg

    Theγ decay in the radiative fusion reaction90Zr+90Zr→180Hg+xγ has been observed in an array of NaI detectors. States up to 6+ in the yrast sequence of180Hg are tentatively assigned and suggest the coexistence of ...

    Evidence for264108, the heaviest known even-even isotope

    We have observed the decay of one atom of the doubly even isotope 108. We observed α-decay with a halflife, of (76 −36 +364 ) Μs. The full α-decay energy could ...

    Element 107

    We identified twoα-emitting isotopes of element 107 with masses of 261 and 262 respectively by parent-daughter correlations. For the isotope with mass 262 we found two transitions with (102±26) ms and (8.0±2.1) m...

    Breakdown of the compound-nucleus model in the fusion-evaporation process for110Pd+110Pd

    The fusion of the massive systems110Pd+104Ru and110Pd+110Pd was uniquely identified by observing the a decay of the evaporation residues. The observed distribution of the fusion cross section on the different eva...

    Decay of the compound nucleus179Au formed in the cold fusion reaction90Zr+89Y

    For the compound nucleus179Au formed at an excitation energy of 26 MeV in the fusion reaction90Zr+89Y, the energy spectra of promptly emitted protons,α particles andγ rays were measured in concidence with the eva...

    Total decay-energy measurement in the fusion reactions90Zr(89Y,p)178Pt and90Zr(89Y, α)175Ir

    In the fusion reactions90Zr(89Y,p)178Pt and90Zr(89Y,α)175Ir the sum energy of all emittedγ rays as well as the energy of the promptly emitted charged particle were measured. From these data the mass-excess values...
