| description | The challenge of isotopic identification over a wide angular distribution has limited the measurement of neutron-rich nuclei produced via the multinucleon transfer (MNT) process. To investigate the optimal detection angles for the N=126 isotones, we propose a method to construct the reasonable scattering angles of the MNT products in the dinuclear system model (DNS-sysu). The reactions ^{136,144}Xe+^{208}Pb are investigated. The calculated results are in rather good agreement with the available experimental data in the reaction ^{136}Xe+^{208}Pb. The entrance channel effects on the scattering angle are investigated. It is found that the scattering angular distribution strongly depends on the isospin and the impact parameter of the collision system. The optimal angle ranges for detecting N=126 neutron-rich nuclides ^{204}Pt, ^{203}Ir, ^{202}Os, and ^{201}Re in the ^{136}Xe+^{208}Pb reaction at the incident energy E_{c.m.}=526MeV are predicted. Our results suggest that the angle range of 45^{∘}⩽θ_{lab}⩽50^{∘} is most favorable for detecting unknown N=126 isotones. Given the current difficulties in separating and identifying experimental MNT fragments, the results of this Letter could provide significant contributions to future experiments. |
