Competition between d/t-capture and α-capture in ^6,7Li+¹²⁴Sn and ^6,7Li+¹⁵⁹Tb reactions

In our recent work, we have shown some remarkable differences in individual ICF channel cross-sections in ^6,7Li induced nuclear reactions. It is observed that the cross-sections for deuteron-capture are of similar magnitude as the α-capture, in case of ⁶Li projectile, while the triton-capture is dominant than α-capture in case of ⁷Li 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-section for α-capture is more compared to α-capture in case of ⁷Li but this argument does not hold with limited ⁶Li data with ²⁰⁹Bi and ¹⁹⁷Au targets. For further investigation of this behavior in individual ICF data, we have performed experiment with ^6,7Li on ¹²⁴Sn target and utilized the available data for ^6,7Li on¹⁵⁹Tb target
