Description: Updating the periodic table, Albert Ghiorso inscribes "Lw" (lawrencium) in space 103; codiscoverers (l. to r.) Robert Latimer, Dr. Torbjorn Sikkeland, and Almon Larsh look on approvingly. The new element was created at the Heavy Ion Linear Accelerator (Hilac) by bombarding a target of californium (with 98 protons) with boron nuclei (with 5 protons, thus creating a new element with 103 protons. It is the first of the trans- uranium elements to be identified entirely by nuclear, rather than by chemical, means. JG
