摘　　要：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(dσ^(2)/dl_(i)dΘand dσ^(2)/dZdΘ)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.
