Angular distribution of products in multinucleon transfer reactions*

Abstract A method based on the dinuclear system (DNS) is proposed to describe the angular distribution of products in multinucleon transfer (MNT) reactions. By considering fluctuation effects, the angular distributions of reactions involving 136 Xe+ 208 Pb, 136 Xe+ 209 Bi, 86 Kr+ 166 Er, 84 Kr+ 209 Bi, and 84 Kr+ 208 Pb are examined, demonstrating good agreement with experimental data. Moreover, the double differential cross-sections ( and ) of reactions 136 Xe+ 208 Pb and 136 Xe+ 209 Bi are analyzed to explore the mechanism of angular distribution in MNT reactions. Additionally, the optimal angles for detecting N =126 isotopes are determined via an analysis on the influence of proton and neutron numbers of the projectiles on the angular distribution of the N =126 isotopic line. The results of this study can provide valuable insights for experimental detection.
