摘要：

We report the measurement of one-neutron stripping to excited-state cross sections from the weakly bound projectile Li-6 to the Zr-96 target at near-barrier energies by the online gamma-ray spectroscopy method. Transitions of the Zr-97 nucleus were clearly identified by gamma-gamma coincidences. This cross section was found to be much smaller than the previously reported complete-fusion cross section for this system at energies above the barrier, whereas it becomes of the same magnitude around the Coulomb-barrier energy. No evidence of two-neutron transfer was found. We also performed coupled reaction channel calculations for the one-neutron stripping process. The calculation results are discussed.
