Effect of the Charge Asymmetry and Orbital Angular Momentum in the Entrance Channel on the Hindrance to Complete Fusion / E.Khusanov, A.Nasirov, M.Nishonov // Physical Review C [Electronic resource]. – 2024. – Vol. 109, No. 5. – P. 054618. – URL: https://doi.org/10.1103/PhysRevC.109.054618. – Bibliogr.: 22.

The hindrance to complete fusion is studied as a function of the charge asymmetry of colliding nuclei and orbital angular momentum of the collision. The formation and evolution of a dinuclear system (DNS) in the heavy-ion collisions at energies near the Coulomb barrier is calculated in the framework of the DNS model. The DNS evolution is considered as nucleon transfer between its fragments. The results prove that a hindrance at formation of a compound nucleus (CN) is related with the quasifission process, which is breakup of the DNS into products instead to reach the equilibrated state of the CN. The role of the angular momentum in the charge (mass) distribution of the reaction products for the given mass asymmetry of the colliding nuclei has been demonstrated. The results of this work have been compared with the measured data for the quasifission yields in the *1*2C+*2*0*4Pb and *4*8Ca+*1*6*8Er reactions to show the role of the mass asymmetry of the entrance channel.
