Heavy Ion Interactions Around The Coulomb Barrier: Proceedings Of A Symposium, Held In Legnaro, Italy, June 1-4, 1988 (lecture Notes In Physics)

Nuclear Reactions At Energies Near And Below The Coulomb Barrier Have Found Much Interest Since Unexpectedly Large Cross Sections Of Fusion For Heavy Ions Were Discovered Around 1980. This Book Covers The More Important Experimental And Theoretical Aspects Such As Sub-barrier Fusion, Sub- And Near-barrier Transfer, Couplings Of Various Reaction Channels, Neck-formation, The Threshold Anomaly, Spin Distributions And Fusion Of Polarized Ions. The Symposium Also Included A Session Devoted To Mass Spectrometry For Fast Reaction Products. Contents: Sub- And Near-barrier Fusion -- Fusion And Quasi-elastic Reactions -- Spin Distribution -- Elastic Scattering And Threshold Anomaly -- Concluding Remarks -- Recoil Mass Spectrometers -- List Of Participants.
