天体中丰中子和超重元素的形成

Formation of neutron-rich and superheavy elements in astrophysical objects

S. K. Patra, R. N. Panda

摘要:

本文计算了丰中子重核以轻奇异同位素为射弹的反应截面和熔合截面。富中子Pb和U同位素的结果显示为代表的目标和He,B作为弹丸。本文用Gluaber模型和耦合道公式计算了各种情况下的反应截面和熔合截面,并在此基础上预测了天体核合成中的快中子/轻核俘获r过程中重、超重和超超重元素的形成。

英文摘要:

We calculate the reaction and the fusion cross-sections of neutron-rich heavy nuclei taking light exotic isotopes as projectiles. Results of neutron-rich Pb and U isotopes are demonstrated as the representative targets and He, B as the projectiles. The Gluaber Model and the Coupled Channel Formalism are used to evaluate the reaction and the fusion cross-sections for the cases considered.Based on the analysis of these cross-sections, we predict the formation of heavy, superheavy and super-superheavy elements through rapid neutron/light nuclei capture r-process of the nucleosynthesis in astrophysical objects.
