Pairing Correlation Study in the ⁴⁰ Ar + ²⁰⁸ Pb Multinucleon Transfer Reaction

摘要

The ⁴⁰ Ar + ²⁰⁸ Pb multinucleon transfer reaction has been studied at E _lab = 255 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 measured. Angular distributions were measured in a wide angular range by matching different spectrometer angular settings. Absolute cross sections were obtained by careful evaluation of the spectrometer response function. These cross sections for different transfer channels allow the discussion of the role played by nucleon–nucleon correlations.
