Query: Potential and limitations of nucleon transfer experiments with
  radioactive beams at REX-ISOLDE   As a tool for studying the structure of nuclei far off stability the
technique of gamma-ray spectroscopy after low-energy single-nucleon transfer
reactions with radioactive nuclear beams in inverse kinematics was
investigated. Modules of the MINIBALL germanium array and a thin
position-sensitive parallel plate avalanche counter (PPAC) to be employed in
future experiments at REX-ISOLDE were used in a test experiment performed with
a stable 36S beam on deuteron and 9Be targets. It is demonstrated that the
Doppler broadening of gamma lines detected by the MINIBALL modules is
considerably reduced by exploiting their segmentation, and that for beam
intensities up to 10^6 particles/s the PPAC positioned around zero degrees with
respect to the beam axis allows not only to significantly reduce the gamma
background by requiring coincidences with the transfer products but also to
control the beam and its intensity by single particle counting. The predicted
large neutron pickup cross sections of neutron-rich light nuclei on 2H and 9Be
targets at REX-ISOLDE energies of 2.2 MeV A are confirmed.
