| Abstract: | Using an advanced statistical model, we have studied the fusion reactions of all possible quadrupole deformation configurations, such as $$\it \beta_{2P}$$ β 2P = +ve, 0, −ve, and targets with $$\it \beta_{2T}$$ β 2T = +ve, 0, −ve to synthesize nuclei 254No, 191Po, and 285Ts. In this regard, we analyzed different projectile target combinations to synthesize 254No, 191Po, and 285Ts nuclei. Fusion cross sections, compound nucleus formation probability, and survival probability are all influenced by the deformation effects of both the projectile and the target rather than the entrance channel effects. We observed that the prolate and spherical combination of projectile and target yields larger cross sections when compared to other combinations studied. The larger cross section of 1.34 nb, 0.754 mb, and 0.74 pb was observed for the fusion reaction of 210Pb(47Ca,3n)254No, 146Gd(47Ca,2n)191Po, and 215Ac(72Ni,2n)285Ts, respectively. This study examined evaporation residue cross sections for No, Po, and Ts nuclei at optimal energy, finding larger production cross sections in all cases when the projectile and target assumed spherical shapes. In order to better comprehend the many facets of heavy ion interactions between deformed and spherical nuclei, deformation must be extensively studied in both theoretical and experimental investigations.
