[en] The topics of the symposium are sub- and near-barrier fusion, limitations to fusion, compound nucleus decay and spectroscopy, incomplete fusion processes, and fragmentation and liquid-gas phase transition. Separate abstracts were prepared for 54 papers in these proceedings
[en] We have studied the effects of the shape of the fusion potential on the fusion cross sections in heavy-ion reactions within the framework of the direct reaction theory of fusion. We have assumed a fusion potential with a smooth Fermi-type surface, treating the radius and diffuseness as parameters. It turns out that the fusion cross sections below the barrier are very sensitive to the diffuseness, for a given radius parameter. We also find that the diffuseness should be small in order to be consistent with the concept of a direct reaction and recently accumulated data for the spin distributions of the compound nucleus.

[en] We have used two different folding models for the construction of the real nuclear potential for very heavy systems in the region 1000 < Z1Z2 < 3000, and computed the corresponding s-wave barrier. A systematic description of the nuclear densities has been undertaken as a starting point for the foldings
[en] The purpose of the paper to develop a formalism to treat rare events, especially when one applies the “active correlation” method to suppress background products in the heavy-ion induced complete fusion nuclear reactions. This formalism is in fact an extension of classical BSC formalism for the case of time multi intervals.
[en] A tentative schematic classification of nuclear processes occurring in heavy ion fusion, based mainly on different interaction times, is given. The distinction between processes, the main parameters of classification and systems is attempted. (author)
[en] On a bright, sunny day in October 1945, a boisterous and jubilant crowd assembled in front of Fuller Lodge to watch as the Army-Navy “E” Award, a prestigious national honor given for “Excellence in Production” during World War II, was presented to the Los Alamos Laboratory. Major General Leslie Groves, the commanding officer of the Manhattan Project; Navy Commodore William S. (Deak) Parsons, the wartime leader of the Laboratory’s Ordnance Division; Robert Sproul, the President of the University of California; and J. Robert Oppenheimer accepted the award on behalf of the Laboratory.
