Abstract.Isotopes of dubnium (element 105) with mass numbers A = 256, 257, and 258 were produced by the reaction 209Bi(50Ti,xn) 259-xDb (x = 1, 2, 3) at projectile energies of (4.59-5.08) AMeV. Excitation functions were measured for the 1n, 2n and 3n evaporation channels. The same position of the excitation function was observed for the 1n channel as for the previously measured 1n channel of the reaction 208Pb(50Ti,1n)257Rf. The measured α-decay data of 257Db and its daughter products resulted… Expand

Abstract.The isotopes 251No and 253No were produced in nuclear reactions 206Pb( 48Ca,3n) 251No and 207Pb( 48Ca,2n) 253No. Radioactive decay of these isotopes and their daughter products has beenExpand
Spectroscopy and single-particle structure of the odd- Z heavy elements 255Lr, 251Md and 247Es
Abstract.The odd-Z isotope 255Lr, its daughter 251Md and grand-daughter 247Es were studied in two experiments performed at GANIL and the University of Jyväskylä. The 255Lr nuclei were produced usingExpand
Alpha-gamma decay studies of 258Db and its (grand)daughter nuclei 254Lr and 250Md
Abstract.The superheavy isotope 258Db was produced in the 209Bi(50Ti, 1n)258Db reaction at GSI, Germany. A detailed $ \alpha$α-spectroscopy study of this isotope and its $ \alpha$α-decay daughterExpand
Alpha-decay properties of 261Bh
The isotope 261Bh was produced in the reaction 209Bi(54Cr, 2n)261Bh and its $ \alpha$ decay has been remeasured. It was found that it populates by an unhindered transition of $ \approx$ 10 MeV anExpand
Experimental identification of spin-parities and single-particle configurations in 257No and its alpha-decay daughter 253Fm.
It was found that the ground-state configuration of (257)No is different from that of lighter N = 155 isotones, and spin-parities of excited states in (253)Fm fed by the alpha decay of (256)No have been identified on the basis of the measured internal conversion coefficients. Expand

The radioactive decay of the isotopes 247Md , 246Md and their daughter products was investigated by means of $ \alpha$ -$ \alpha$ and $ \alpha$ -$ \gamma$ coincidence spectroscopy. The isotopes wereExpand
Nuclear isomers in 259Sg and 255Rf
The production and radioactive decay of 259Sg and its daughter products were investigated using α-decay spectroscopy and spontaneous-fission measurements. The isotope was produced in theExpand
Investigation of electron capture decay of 258Db and $\alpha$α decay of 258Rf
Abstract.Electron capture decay of 258 Db was measured directly via delayed coincidences between K X-rays and/or conversion electrons (from the electron capture decay), and spontaneous fission orExpand
