The neutron-deficient isotopes 257,258105 were produced in the reaction 27Al+236U in 6n and 5n evaporation channels, respectively. The evaporation residues emerging from the target were separated in-flight from the projectiles and from products of different nuclear reactions by the electrostatic separator VASSILISSA [1]. The isotopes were then implanted into position-sensitive silicon detectors and identified using the α-α-correlation method. The measured production cross-section is σ(5n)=(0.45…

Evaporation residues from the heavy-ion fusion reaction50Ti on209Bi were investigated. They were separated from the projectile beam by the velocity filter SHIP and identified after implantation into

REVIEW ARTICLE: Recent advances in the discovery of transuranium elements

The heaviest known elements at present, the transactinides, ranging from element 104 to element 109, are the subject of this paper. It will start with a brief historical review on their

On the Production of Heavy Elements by Cold Fusion: The Elements 106 to 109

The production of isotopes of elements 106 through 109 is considered. Techniques involving heavy ion fusion reactions are discussed including shell corrections, cross sections, velocity separators.
