Narrow Results

Quasifission barriers were studied in the superheavy region $104\le Z\le 126$ using different projectile-target combinations. The different entrance channels parameters on quasifission barriers give an insight into the formation of compound nuclei and quasifission process. The quasifission barriers are more systematic for ${\chi }_m=0.25{\chi }_{\mathrm{\text{CN}}}+0.75{\chi }_{\mathrm{\text{eff}}}$. The effect of compound nucleus fissility ${\chi }_{\mathrm{\text{CN}}}$ and effective entrance channel fissility ${\chi }_{\mathrm{\text{eff}}}$ on quasifission barriers were investigated. The quasifission barriers are strongly influenced by ${\chi }_{\mathrm{\text{CN}}}$ and ${\chi }_{\mathrm{\text{eff}}}$ entrance channel parameters. The detailed investigations of entrance channel parameters on quasifission barriers provide a thorough understanding of compound nuclei formation in the superheavy element in the region $104\le Z\le 126$. Eventually, this study helps in the selection of projectile-target combinations to synthesis of superheavy nuclei.
