    One-neutron stripping process between Li-6 and Bi-209 was studied at 28, 30, and 34 MeV using the in-beam gamma-ray spectroscopy method. The gamma-gamma coincident analysis clearly identified two gamma-rays feeding the ground and long-lived isomeric states, which were employed to determine the cross section. The one-neutron stripping cross sections were similar to the cross sections of complete fusion in the Li-6+Bi-209 system, but the one-neutron stripping cross sections decreased more gradually at the sub-barrier region. A coupled-reaction-channel calculation was performed to study the detailed reaction mechanism of the one-neutron stripping process in Li-6. The calculations indicated that the first excited state of Li-5 is critical in the actual one-neutron transfer mechanism, and the valence proton of Bi-209 can be excited to the low-lying excited state in (Li-6,Li-5) reaction, unlike in the (d,p) reaction.
