Incomplete fusion reactions for ${}_{19}F+{}_{169}\mathrm{Tm}$: Measurement of recoil range distributions

This present study explores the role of incomplete fusion in heavy-ion reactions alongside complete fusion, examining recoil ranges of populated residues. An attempt has been made to distinguish between complete and incomplete fusion contributions by analyzing linear momentum transfer from the projectile to the target nucleus. Employing the recoil-catcher activation technique, forward recoil range distributions for the ${}_{19}F+{}_{169}\mathrm{Tm}$ system at energies around 96 and 106 MeV have been measured. Analysis of these recoil range distributions reveals characteristics of complete and incomplete fusion processes. Complete fusion reactions show larger recoil ranges, signifying comprehensive linear momentum transfer. On the other hand, residues exhibiting smaller recoil ranges result from partial linear momentum transfer due to incomplete fusion of the projectile. The forward recoil range distributions indicate an admixture of full and partial linear momentum transfer components in reactions with $\alpha$ particles in the exit channels. This behavior suggests projectile breakup caused by the Coulomb effect, offering valuable insights into fusion process dynamics.
