On verso: "One of America's Leading Atomic Research Centers. Argonne National Laboratory, located ten miles southwest of Chicago, Illinois, operates two Van de Graff positive ion accelerators. The 5 MEV precision machine shown accelerates protons, alpha particles or deuterons, or produces neutrons by charged particle reactions. Typical investigations include total neutron cross sections, angular distributions, resonance scattering, energy level schemes, and studies of the lifetimes of nuclear excited states."]]>
