Chemical separation of nielsbohrium as ekatantalum in the form of anhydrous bromide. II. Experiments with spontaneously fissioning nielsbohrium isotopes

Creators

Description

The behavior of nielsbohrium and niobium--bromine compounds was compared using the frontal thermochromatography technique. The nielsbohrium spontaneous fission isotope was produced by bombarding an americium-243 target with neon-22 ions. The niobium-90 isotope was produced simultaneously in nuclear reaction with bromine. The adsorption zone of nielsbohrium is formed at a slightly higher temperature as compared with niobium and tantalum. Similar results were obtained in previous investigations of the properties of chlorine compounds of element 105. This agrees with the expected properties of nielsbohrium as ekatantalum. (auth)
