By: Paul Preuss, Lawrence Berkeley National Laboratory A classical diagram of a krypton atom (background) shows its 36 electrons arranged in shells. Researchers have measured oscillations of quantum states (foreground) in the outer orbitals of an ionized krypton atom, oscillations that drive electron motion. by Paul Preuss. Technicians work on the magnet for the 88-inch cyclotron, 1960. Element 105 — subject of a bitter scientific dispute and still known as hahnium to its Berkeley Lab discoverers — followed in 1970. In 1969 controversy erupted over using Lab facilities to host political speeches; for the first time, prior approval was To build a small research laboratory equipped with one of Berkeley Lab's generators would cost about $5 million, Leung estimates. To get a comparable flux of neutrons would require a thousand commercial neutron tubes, costing $100 million. High-energy accelerators are another order of magnitude more expensive to build.
