Near-barrier fusion and barrier distribution ofNi58+Fe54

Abstract

Near-and sub-barrier fusion cross sections have been measured for the system 58 Ni + 54 Fe, and the fusion barrier distribution has been extracted. The measured cross sections cover the range from 1 µb up to around 500 mb. Close analogies are found between the extracted barrier distribution and the available data on 58 Ni + 60 Ni, indicating the dominating influence of complex surface vibrations on the fusion of 58 Ni + 54 Fe. The present data on 58 Ni + 54 Fe are well reproduced by standard coupled-channels calculations in the measured energy range, including quadrupole and octupole phonons in both colliding nuclei.

“…The BD of 58 Ni + 54 Fe was already reported in Ref. [14]. Figure 3 indicates that the BD of 48 Ti + 58 Fe extends more toward low energies, and this is sufficient to explain the larger cross sections (Fig.…”

Study of The Breakup Channel Effect on The Semiclassical and Quantum Mechanical Calculations for The Light and Medium System

“…The best calculated chisquare value obtained is which corresponds to the full quantum mechanical calculation including coupled channel are in the best agreement with the experimental data for the fusion barrier distribution , while chisquare value is for , which corresponds to the semiclassical calculations including coupling are in the best agreement with experimental data. Figure 2 panel (a) and (b) presents the comparison between our theoretical calculations for the total fusion reaction cross section and the fusion reaction barrier distribution using both semiclassical and quantum mechanical calculations with the corresponding experimental data for the system 15 N+ 54 Fe the experimental data for this system are obtained from Ref [36]. The dashed blue and red curves represent the semiclassical and full quantum mechanical calculations without coupling, respectively.…”

Possibilities of synthesizing new proton-rich nuclei with 40 ≤ Z ≤ 60 using multinucleon transfer reactions *

“…Fig. 10 shows the fusion-evaporation cross sections [56][57][58][59][60][61][62][63][64][65], spallation or fragmentation cross sections [66][67][68], and the experimental data [54] and measured MNT cross sections for some nuclear isotopes with . The theoretical data of MNT reaction are obtained from the Ca+ Te reaction in Fig.…”
