Abstract

Calculations of total fusion cross sections of the weakly bound nuclei 6,7 Li with a variety of targets at energies around the Coulomb barrier are presented. Special emphasis is focused on the effects that resonance states, l=2, J π =3 + , 2 + , 1 + of 6 Li, and l=3, J π =7/2 - , 5/2 - of 7 Li, have on fusion. The study uses the Continuum-Discretized Coupled-Channel (CDCC) framework to calculate total fusion, from which the effects of couplings to resonance states are extracted. Resonance states with shorter half-lives have a more important effect on total fusion at energies below and around the Coulomb barrier, where incomplete fusion dominates. On the other side, resonance states with longer half-life, act as quasi-bound inelastic states, thus, these states have a more important role on complete fusion than on incomplete fusion.

6,7 li与靶材27Al, 28Si, 144Sm, 198Pt和209Bi全聚变的CDCC计算:共振态的影响

本文给出了在库仑势垒周围的能量范围内，以各种目标为目标的弱束缚核6,7 Li的总聚变截面的计算。特别强调了6 Li的共振态l=2, J π =3 +， 2 +， 1 +和7 Li的共振态l=3, J π =7/2 -， 5/2 -对核聚变的影响。本研究采用连续离散耦合通道(CDCC)框架计算总融合，从中提取耦合对共振态的影响。半衰期较短的共振态对库仑势垒以下和周围能量的总聚变有更重要的影响，在那里不完全聚变占主导地位。另一方面，具有较长半衰期的共振态充当准束缚非弹性态，因此这些态对完全聚变的作用比不完全聚变的作用更重要。
