“…The situation is different in the case of heavy reaction systems, because the decay of the excited compound nucleus through the emission of charged particles can be negligible and the separate measurements of the CF cross section can be achieved. Many measurements of the CF cross sections have been performed [4][5][6][7][8][9][10][11][12][13][14]. * sgzhou@itp.ac.cn Several methods have been adopted to investigate the influence of the breakup on fusion reactions around the Coulomb barrier [15][16][17][18][19][20].…”

A large number of complete fusion excitation functions of reactions including the breakup channel were measured in recent decades, especially in the last few years. It allows us to investigate the systematic behavior of the breakup effects on the complete fusion cross sections. To this end, we perform a systematic study of the breakup effects on the complete fusion cross sections at energies above the Coulomb barrier. The reduced fusion functions F (x) are compared with the universal fusion functions which are used as a uniform standard reference. The complete fusion cross sections at energies above the Coulomb barrier are suppressed by the breakup of projectiles. This suppression effect for reactions induced by the same projectile is independent of the target and mainly determined by the lowest energy breakup channel of the projectile. There holds a good exponential relation between the suppression factor and the energy corresponding to the lowest breakup threshold.

“…Unfortunately, D f us could not be extracted from the reported fusion cross sections [7,18], because only a few data points were available for differentiation. Therefore, a rough comparison of the experimental D qel was made with the theoretical D f us , extracted EPJ Web of Conferences 163, 00039 (2017) DOI: 10.1051/epjconf/201716300039 FUSION17 from the fusion cross sections calculated using the coupled channels code, CCFULL [19].…”

Abstract. Quasielastic scattering cross sections for the reaction 7 Li+ 159 Tb have been measured at large backangles, at energies around the Coulomb barrier. The quasielastic barrier distribution has been extracted from the measured quasielastic scattering excitation function, including and excluding α particle contribution. The peak of the quasielastic barrier distribution including α particle contribution shows a shift towards higher energy compared to the peak of the distribution without α particles. The quasielastic barrier distribution when compared to the calculated fusion barrier distribution, appears to show reasonable agreement for the system.

“…We have used the available ICF cross-section data for 6,7 7 Li+ 159 Tb [19] reactions are compared and shown with filled circle and filled diamond symbols, respectively. It is evident from this figure that t-ICF cross-sections are much more dominant compared to ones for α-ICF crosssections at all the measured energies with 7 Li projectile.…”

“…It is evident from this figure that t-ICF cross-sections are much more dominant compared to ones for α-ICF crosssections at all the measured energies with 7 Li projectile. Intuitively, we expect this behavior as triton while approaching the target sees lower Coulomb barrier compared to alpha particle approaching the target, hence the cross- 7 Li+ 197 Au [18], and (d) 7 Li+ 159 Tb [19] reactions are compared with filled circle and filled diamond symbols, respectively. It is evident from the figure that t-ICF is dominant compared to α-ICF at all the measured energies.…”

Abstract. We have included breakup effects explicitly to simultaneously calculate the measured cross-sections of the complete fusion, incomplete fusion, and total fusion for 6,7 Li projectiles on various targets using the Continuum Discretized Coupled Channels method. The breakup absorption cross-sections obtained with different choices of short range imaginary potentials are utilized to evaluate the individual α-capture and d/t-capture cross-sections and compare with the measured data. It is interesting to note, while in case of 7 Li projectile the cross-sections for triton-ICF/triton-capture is far more dominant than α-ICF/α-capture at all energies, similar behavior is not observed in case of 6 Li projectile for the deuteron-ICF/deuteron-capture and α-ICF/α-capture. Both these observations are also corroborated by the experimental data for all the systems studied.
