Abstract

Multinucleon transfer channels, populated in the inverse kinematic reaction ^197Au+^130Te at E_lab = 1.07 GeV, were studied by means of a high-resolution kinematic coincidence set-up composed of the large acceptance magnetic spectrometer PRISMA coupled to a new detection system acting as second arm. The comparison of the experimental mass-mass correlation matrix with Monte Carlo simulations allowed us to investigate the role of neutron evaporation in the population of neutron-rich heavy nuclei around A = 200.

Highlights

  • The magnetic spectrometer PRISMA [8], acting as main arm of the coincidence set-up, and its focal plane detector were settled in order to select and identify with high resolution the light target-like fragments (TLF)

  • We focus here on pure neutron transfer channels

  • The inset shows the same set-up, the mass-mass correlation distribution in logarithmic scale and the matrix shown in Figure 3 was multigaussian fit used to estimate the constructed associating to each light yields of neutron transfer channels
