摘要

通过在线特征 γ 射线探测技术测量了 Li7+Tl205 反应在接近势垒能量时的完全和不完全聚变截面。与耦合通道计算相比,发现能量高于库仑势垒时的完全聚变(CF)截面被抑制了 26%。研究还发现,本系统在能量归一化为库仑势垒时的核聚变截面也低于强结合射弹形成类似化合物核时的截面。在 CF 截面中观察到的抑制与测得的总不完全聚变(ICF)截面相一致。在 ICF 截面中,发现在所有测得的能量下,t 捕获比 α 捕获占主导地位。对现有的 Li7 射弹 CF、ICF 和总聚变数据进行了系统研究。

Fusion ofLi7withTl205at near-barrier energies

Fusion ofLi7withTl205at near-barrier energies
The complete and incomplete fusion cross sections for the Li7+Tl205 reaction were measured at near barrier energies by the online characteristic γ-ray detection technique. The complete fusion (CF) cross sections at energies above the Coulomb barrier were found to be suppressed by 26% compared to the coupled channel calculations. Reduced fusion cross sections for the present system at energies normalized to the Coulomb barrier were also found to be systematically lower than those with strongly bound projectiles forming a similar compound nucleus. The suppression observed in CF cross sections is found to be commensurate with the measured total incomplete fusion (ICF) cross sections. In the ICF cross sections, t-capture is found to be dominant than α-capture at all the measured energies. The systematic study of available CF, ICF, and total fusion data with the Li7 projectile is performed.
