Abstract

Mendelevium-256 was obtained by irradiating of Bk-249 with Ne-22 ions in the external beam of U-300 cyclotron. An efficient ionexchanging method of medelevium isolation and separation from nuclear reaction products have been developed in which a column with cation exchanger and zinc amalgam and 1M HCl solutions as eluents were used. Under these conditions mendelevium has been shown to be reduced and washed out as an alkaline earth element. The ionic radius of Md2+ has been estimated from a correlation of the elution peak positions with ionic radius of several divalent elements. This value was used to calculate the heat of hydration of Md2+ ion.
