摘要： 1. IN A PROCESS FOR THE SYNTHESIS OF ELEMENT 95, THE STEPS WHICH COMPRISE DISSOLVING A NEUTRON-IRRADIATED MASS OF URANIUM CONTAINING A TRANSURANIC FRACTION COMPRISING PREDOMINANTLY PLUTONIUM WHICH CONTAINS AT LEAST ABOUT 0.01% OF THE ISOTOPE 94**241 AND A DETECTABLE QUANTITY OF ELEMENT 95 IN AN AQUEOUS ACIDIC SOLUTION, OXIDIZING THE PLUTONIUM CONTAINED IN THE RESULTING SOLUTION TO A VALENT STATE GREATER THAN +4, REMOVING URANIUM FISSION PRODUCTS AND ELEMENT 95 THEREFROM BY MEANS OF A WATER-INSOLUBLE RARE EARTH SALT CARRIER, DISSOLVING THE CARRIER PRECIPITATE THUS OBTAINED, INTRODUCING FLOUSILICATE IONS INTO THE RESULTING SOLUTION, CONTACTING SAID SOLUTION WITH A WATER-INSOLUBLE RARE EARTH SALT CARRIER FOR SAID FISSION PRODUCTS AND SEPARATING THE RESULTING PRECIPITATE, ADDING SUFFICIENT HYDROFLUORIC ACID TO RENDER THE SUPERNATANT SOLUTION THUS OBTAINED FROM ABOUT 3 TO 6 M WITH RESPECT THERETO, THEREAFTER CONTACTING THE SOLUTION WITH A WATER-INSOLUBLE RARE EARTH SALT CARRIER FOR ELEMENT 95, AND SEPARATING THE CARRIER PRECIPITATE FROM THE SOLUTION.
