Abstract

Background: Quasifission reactions occur in fully damped heavy-ion collisions without the formation of an equilibrated compound nucleus, leading to the formation of fragments with properties similar to those in fission reactions. In particular, similar shell effects are expected to affect fragment formation in both fission and quasifission. Experimentally, the role of shell effects in quasifission is still debated, and further theoretical predictions are needed.

形成 Th226 复合核的反应中准裂变的壳效应

背景：准裂变反应发生在完全阻尼的重离子碰撞中，没有形成平衡的复合原子核，因此形成的碎片具有与裂变反应类似的性质。特别是，类似的壳效应预计会影响裂变和准裂变中碎片的形成。在实验中，壳效应在类裂变中的作用仍有争议，需要进一步的理论预测。
