In the present work, the in-complete fusion probability has been deduced for 12C+159Tb and 13C+159Tb systems in the energy range ≈ 4-7 MeV/nucleon. The activation technique followed by off-line γ-rays spectroscopy has been used. The results have been compared with the predictions of statistical model code PACE4, which is based on the compound nucleus decay. The ratio of the sum of cross-sections of all measured xn, pxn channels to their corresponding PACE4 predictions are found to be lying close to unity throughout the studied energy range for both the systems, indicating their population via fusion evaporation channels followed by CF processes only. However, the ratio of the sum of cross-sections of all experimentally measured xn, pxn and αxn-channels to their corresponding PACE4 calculations, display significant enhancement over the unity line, indicating the onset and presence of in-complete fusion processes at these energies. The comparison of experimentally measured and systematically deduced in-complete fusion fractions for both the systems reveals a strong projectile structure effect. The probability of in-complete fusion is found to be higher for 12C induced reaction than for one-neutron rich 13C induced reactions on the same target 159Tb. An attempt has been made to study the ICF probability within the frame work of the α-Q-value of the projectiles. Analysis of the data indicates that the α-Q-value of the projectile is an important entrance channel parameter and seems to dictate the probability of ICF at these low energies.
