Abstract

Three-particle correlations in the reaction208Pb+6Li were studied near the Coulomb threshold between\(E_{6_{Li} } = 24\) and 30 MeV. Three reaction mechanisms contribute predominantly to the observed coincidences of the charged particles: 1. Coulomb excitation of the 2.184 MeV,J=3+ state of6Li, followed by the decay intoα+d, 2. Deuteron pick-up of the6Li to the ground state of8Be and sequential decay into twoα-particles and 3. Neutron-transfer to the ground state and the first excited states of209Pb:208Pb(6Li,αp). The last two reaction mechanisms explain the previously measured large contributions to theα-channel relative to thed-channel.
