Fusion mechanism of weakly bound stable (Li and Be) and unstable halo (Li, Be, and B) nuclei is a subject of great interest from the past few years [1,2]. Due to their low breakup threshold, various reaction processes like complete-incomplete fusion (CF-ICF), elastic breakup, and transfer followed by a breakup, appear in the reaction dynamics. Hence, to study the CF-ICF mechanisms and its dependency on entrance channel parameters in Li+Y reaction an experiment was performed at the BARC-TIFR Pelletron facility Mumbai, India, using activation technique within the 2.7–5.7 MeV/nucleon energy range. The γ-spectrometry has been used to identify the residues and residual cross-sections have been measured. A systematic analysis of the complete and incomplete fusion dynamics has been carried out by comparing the measured excitation functions with the equilibrium and pre-equilibrium reaction models in the framework of statistical reaction codes EMPIRE3.2.2 and ALICE19. A strong indication of incomplete fusion has been realized within the energy range considered; hence the strength of incomplete fusion fraction (F) has been deduced. F shows an increasing trend with increasing projectile energy [3]. Further, barrier height and radius parameters extracted from the measured data are in good agreement with the Bass model.
