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.
Highlights
In recent years, there is a lot of data available for complete fusion (CF) cross-sections with 6,7Li and 9Be projectiles on various targets [1,2,3,4,5,6,7,8,9,10,11,12,13]
From the available experimental data, we have highlighted the differences in individual incomplete fusion (ICF) crosssections for 6Li and 7Li projectiles on various targets
The individual ICF cross-sections imply that the d-ICF crosssection is of similar order that of α-ICF cross-section in case of 6Li, while t-ICF cross-section is much more than α-ICF cross-section in case of 7Li
Summary
There is a lot of data available for complete fusion (CF) cross-sections with 6,7Li and 9Be 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.
