A new isotope of element 103 with mass number 256 was synthesized by means of the nuclear reaction95Am243 (8O18′ 5n)103Lw256.The detection and identification of103Lw256 was made through the isotope100Fm252, a product of electron capture in101Mv252 produced by α-decay of103Lw256. The half-life of103Lw256 is 45 sec.The energy dependence of the103Lw256 production cross section in the95Am243+8O13 reaction was investigated. It was the shape of a curve with a maximum at an8O18 ion energy ≈96 MeV (lab…

Abstract Production cross-sections of the isotope 256Lr in the 249,250,251Cf +11B, 243Am +18O, and 248Cm +14N reactions were measured using a He/KCl gas-jet transport system and a rotating wheel
The transuranium elements: From neptunium and plutonium to element 112
Beginning in the 1930`s, both chemists and physicists became interested in synthesizing new artificial elements. The first transuranium element, Np, was synthesized in 1940. Over the past six
Evolution of the periodic table through the synthesis of new elements
Abstract This brief introduction to the synthesis and chemistry of elements discovered since 1940 is focused primarily on Z=93–118. The goal of this work is not to simply catalogue the nuclear fusion
