Description: Explains transmutations of metals in its nuclear science context. Shows how a minute quantity of berkelium is produced by bombarding curium with deuterons from a cyclotron and how the berkelium is separated and purified behind the thick walls of newlyconstructed 'HOT LABORATORY' for research with manmade elements. , For centuries men have dreamed of turning common elements such as lead and zinc into more precious metals such as gold and silver. Today, nuclear scientists are looking beyond this and are inventing new elements which are more valuable than gold. This program, “The Alchemist’s Dream,” looks into these new elements –like curium and berkelium –which were unheard of a few years ago. Using an instrument called a cyclotron –an atom smasher –scientists at the United States Atomic Energy Commission’s Argonne National Laboratory are making new elements which do not exist in nature. In a manner of speaking, scientists at Argonne are working in an “atomic shooting gallery.” Houses in a special room behind seven –foot thick concrete doors, a cyclotron bombards target atoms of curium with a beam of a special variety of hydrogen nuclei, resulting in the making of a new elements, berkelium, one of eleven elements which have been “invented” by science. Behind heavy concrete walls, painstaking precautions are taken in the manufacture of these new elements because of harmful radiation, a byproduct of atom splitting. Though these experiments yield only small amounts of the new elements, they enable scientists to work out their chemical properties. This research provides new information on how atoms are put together. It also tells the scientists what to expect when larger quantities of the new elements are available. Already, some of these man-made elements are furnishing the power for satellites and remote weather stations. A small quantity of one of the new man-made elements, californium, scientists predict, could produce enough energy to do the job of a nuclear reactor weighing several tons.
