NEUTRON TRANSFER-REACTIONS WITH RADIOACTIVE BEAMS

Neutron transfer experiments under inverse kinematics have been propos ed as a spectroscopic tool with second-generation radioactive nuclear beam facilities. We illustrate typical experimental criteria by exampl es involving the spectroscopy of light neutron-rich nuclei. Calculatio ns have been performed to estimate the energy resolution attainable. T he relative importance of Various contributions to the resolution is s tudied for a range of masses and incident energies, for both fragmenta tion and on-line isotope separator facilities. The detection of the he avy product of the reaction by an energy-loss spectrometer and that of the recoil light particle by a charged particle array is compared. It is shown that the coincidence detection of the heavy ion and light pa rticle may improve the energy and angular resolution, while reducing b ackground from projectile breakup and scattering.
