Role of nuclear surface tension coefficients in the isotopic dependence of fusion dynamics for neutron-rich colliding nuclei: New parametrization of fusion barriers

“…Recent progress of the experimental techniques enable us to get access to the radioactive neutron-rich (or proton-rich) beams and thus to synthesize new heavy nuclei with neutronrich/-deficient content [23][24][25]. So far, extensive efforts have been made to answer the question: how do the additional/ removal neutrons affect the shape of interaction potential and fusion probabilities for different isotopic systems which include either (or both) proton-rich (for example 48 Ni+ 48 Ni and 34 Ca+ 34 Ca) or neutron-rich (for example 64 Ni+ 64 Ni and 18 O+ 28 Si) colliding nuclei [16,18,20,22]. In those studies, various theoretical approaches have been adopted to calculate the heavy ion-ion potential.…”

“…It is worth mentioning that the change in the neutron number not only alters the barrier heights and positions, it also changes the surface diffuseness of the fusion barrier [26]. In recent years, various efforts have been made to study the fusion dynamics of neutron rich nuclei using statistical and alternative theoretical models [27][28][29][30][31].…”
