Description

Research carried out during the contract period by R.A. Bryan, principal investigator, and associates R.B. Clark and B.J. VerWest is investigated. The research has centered on the nucleon--nucleon interaction from threshold up through intermediate energies (T/sub L/ less than or equal to 1 GeV). A major portion of time was devoted to the inelastic channel NN ..-->.. NN..pi.. and has resulted in a peripheral model for this reaction which gives good fits to the world data around 800 MeV. The present status of elastic NN scattering above the ..pi..-production threshold was reviewed extensively, new parameterizations were developed and data bases ... continued below

Description

Research carried out during the contract period by R.A. Bryan, principal investigator, and associates R.B. Clark and B.J. VerWest is investigated. The research has centered on the nucleon--nucleon interaction from threshold up through intermediate energies (T/sub L/ less than or equal to 1 GeV). A major portion of time was devoted to the inelastic channel NN ..-->.. NN..pi.. and has resulted in a peripheral model for this reaction which gives good fits to the world data around 800 MeV. The present status of elastic NN scattering above the ..pi..-production threshold was reviewed extensively, new parameterizations were developed and data bases assembled for analyses of this process. The three point ..pi..NN vertex was studied in the context of the dual Veneziano model where all three particles can be taken off shell. It was shown that this form of off-shell dependence in NN interaction models, hereto ignored, can have important consequences. Finally, initial work was completed in an attempt to use the constituent interchange quark model to constrain the short range behavior of the meson-exchange models of the NN interaction. A list of publications is included.
