Probable projectile-target combinations for the synthesis of superheavy element 302 120 have been studied taking Coulomb and proximity potential as the interaction barrier. The probabilities of compound nucleus formation, P CN for the projectile-target combinations found in the cold reaction valley of 302 120 are estimated. At energies near and above the Coulomb barrier, we have calculated the capture, fusion and evaporation residue cross sections for the reactions of all the probable projectile-target combinations so as to predict the most promising projectile-target combinations for the synthesis of SHE 302 120 in heavy ion fusion reactions. The calculated fusion and evaporation cross section for the more asymmetric ("hotter") projectile-target combination is found to be higher than the less asymmetric ("colder") combination. It can be seen from the nature of quasi-fission barrier height, mass asymmetry, probability of compound nucleus formation, survival probability and excitation energy,
