    Carefully prepared and well-characterized Bi1.7Pb0.3 Sr2Ca2Cu3Ox samples were studied by means of differential scanning calorimetry, thermogravimetry, and room and high temperature x-ray diffraction in different atmospheres. It is found that the decomposition of Bi1.7Pb0.3Sr2Ca2Cu3Ox strongly depends on the given conditions. In argon atmosphere, the sample begins to decompose at 850 °C, and finally decomposes mainly into Bi2Sr2CuOx, Cu2O, CaO, and (Sr,Ca)2O3; in air, it decomposes at 880 °C, into Bi2Sr2CuOx, Bi2Sr2CaCu2Ox, Bi1.7Pb0.3Sr2Ca2Cu3Ox, and (Sr,Ca)O; in oxygen, it decomposes at 900 °C, into Bi2Sr2CuOx, Bi2Sr2CaCu2Ox, Bi1.7Pb0.3Sr2Ca2Cu3Ox, and (Sr,Ca)2O3. The process of the melting was in situ studied by high temperature x-ray diffraction and a quenching method. This study gives some hints for growing single crystals of Bi1.7Pb0.3Sr2Ca2Cu3Ox and how to introduce pinning centers into Bi2Sr2CaCu2Ox and Bi1.7Pb0.3Sr2Ca2Cu3Ox. © 1995 American Institute of Physics.

    Abstract. Detailed fine-structure $\alpha$ -decay studies of 188,190Bi were performed using the complete-fusion reactions of 50,52Cr ions with a 142Nd target at the velocity filter SHIP. The evaporation residues were separated in-flight and subsequently identified on the basis of recoil- $\alpha$ , recoil- $\alpha$ - $\gamma$ /X-ray and excitation function measurements. Improved data on the $\alpha$ -decay of 188,190Bi were obtained and a number of new low-lying excited states in the daughters 184,186Tl were observed. An intruder, presumably 10- state was identified in 184Tl, extending the systematics of such states in the odd-odd Tl nuclei beyond the neutron mid-shell at N = 104. Some technical aspects of experiment at recoil separators are also discussed.

    Abstract. Alpha-decay of the new nuclide 184Bi has been studied in the complete-fusion reaction 93Nb(94Mo, 3n)184Bi at the velocity filter SHIP. The evaporation residues were separated in-flight and subsequently identified on the basis of recoil- $\alpha$ , recoil- $\alpha$ - $\gamma$ analysis and excitation functions measurements. Two $\alpha$ -decaying isomeric states in 184Bi with half-life values of 13(2) ms and 6.6(1.5) ms were identified. The $\alpha$ -branching ratio of 180Tl was deduced for the first time as $b_\alpha = (2 --12)\%$ . Improved data on the fine-structure $\alpha$ -decay of 186Bi were obtained in the 93Nb(95Mo, 2n)186Bi reaction. A similarity of the decay energies and half-life values of 184,186Bi is pointed out and a possible explanation for this effect is suggested.

    Abstract: The even-even nucleus 270110 was synthesized using the reaction 64Ni + 207Pb. A total of eight α-decay chains was measured during an irradiation time of seven days. Decay data were obtained for the ground-state and a high-spin K isomer. The new nuclei 266Hs and 262Sg were identified as daughter products after α-decay. Spontaneous fission of 262Sg terminates the decay chain. The measured data are in agreement with calculations using the macroscopic-microscopic model and with self-consistent HFB calculations with Skyrme-Sly4 interaction.
