The Pairing Correlation Study in the ~(40)Ar+~(208)Pb Reaction

摘要

The multinucleon transfer reaction ~(40)Ar+~(208)Pb has been measured at E_(1ab) = 260 MeV with the large solid angle magnetic spectrometer PRISMA. Mass and charge yields, differential and total cross sections, total kinetic energy loss distributions of different channels were simultaneously studied. Angular distributions were measured in a wide angular range by matching three different angular settings of the spectrometer. Absolute cross sections were obtained after the response function of the spectrometer was evaluated. These cross sections for different transfer channels allow the discussion of the role played by nucleon-nucleon correlations.
