“…This shortcoming can be avoided within a new dynamical quantum approach that includes SCF as well as ICF from the bound state(s) of the projectile [26]. In addition, the comparison of experimental fusion cross sections with either the predictions of coupled-channel (CC) calculations without the breakup and transfer channels [12][13][14][15][16][27][28][29][30][31] or the predictions of a single barrier penetration model (SBPM) [9][10][11] shows that CF cross sections are suppressed owing to the breakup at energies above the Coulomb barrier.…”

Complete fusion excitation functions of reactions involving breakup are studied by using the empirical coupled-channel (ECC) model with breakup effects considered. An exponential function with two parameters is adopted to describe the prompt-breakup probability in the ECC model. These two parameters are fixed by fitting the measured prompt-breakup probability or the complete fusion cross sections. The suppression of complete fusion at energies above the Coulomb barrier is studied by comparing the data with the predictions from the ECC model without the breakup channel considered. The results show that the suppression of complete fusion are roughly independent of the target for the reactions involving the same projectile.

“…These nuclei have unusually low separation energy among its constituents and therefore have a high breakup probability. The nucleus 6 Li breaks up into 4 He + 2 H with separation energy, S α = 1.48 MeV. As a result these nuclei promptly break up during the fusion process of these projectiles with a heavy target nucleus.…”

“…If none of the breakup fragments fuse with the target, then it is called no-capture breakup (NCBU) [3]. Due to breakup, the experimental cross section falls below the theoretically expected value which is also called fusion suppression [2,4,5]. The calculation of breakup yields for reactions initiated by loosely bound projectiles has been done by CDCC as well as classical methods [6].…”

Abstract. We adopt a semi-classical approach for explanation of projectile breakup and above barrier fusion suppression for the reactions 6 Li+ 152 Sm and 6 Li+ 144 Sm. The cut-off impact parameter for fusion is determined by employing quantum mechanical ideas. Within this cut-off impact parameter for fusion, the fraction of projectiles undergoing breakup is determined using the method of classical trajectory in two-dimensions. For obtaining the initial conditions of the equations of motion, a simplified model of the 6 Li nucleus has been proposed. We introduce a simple formula for explanation of fusion suppression. We find excellent agreement between the experimental and calculated fusion cross section. A slight modification of the above formula for fusion suppression is also proposed for a three-dimensional model.

“…In recent years, there is a lot of data available for complete fusion (CF) cross-sections with 6,7 Li and 9 Be projectiles on various targets [1][2][3][4][5][6][7][8][9][10][11][12][13]. The measured complete fusion cross-sections are found to be suppressed compared to the Coupled Channel calculations or One Dimensional barrier penetration model calculations at above barrier 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.
