A study of low-energy incomplete fusion was done by the measurements excitation functions evaporation residues produced in $^{16}\mathrm{O}+^{148}\mathrm{Nd}$ system at energies $\ensuremath{\approx}4--7$ MeV/nucleon. The stacked foil activation technique using offline $\ensuremath{\gamma}$-ray spectrometry employed. Significant enhancements were found measured cross sections from theoretical predictions pace-4 for populated through $\ensuremath{\alpha}$-emission channels. This enhancement...
Abstract Spin distributions for several evaporation residues populated in the 16 O+ 154 Sm system have been measured at projectile energy ≈ 6.2 MeV/A by using charged particle– γ -coincidence technique. The spin of through incomplete fusion associated with ‘fast’ α and 2 -emission channels are found to be entirely different from fusion–evaporation channels. It is observed that mean input angular momentum formed channel relatively higher than complete feeding intensity profile also studied....

Background: In heavy-ion-induced fusion reactions, cross sections in the sub-barrier region are enhanced compared to predictions of one-dimensional barrier penetration model. This enhancement is often understood by invoking deformation and coupling relative motion with low-lying inelastic states reaction partners. However, effects nucleon transfer on below barrier, especially for systems having positive $Q$ value neutron (PQNT) channels, yet be disentangled completely.Purpose: We intend...

Enhancement of fusion cross sections below the interaction barrier has been quite successfully explained by coupled-channels methods. However, extending measurements to deep sub-barrier energies revealed a steeper descent excitation function which could not be standard calculations. Though large number heavy-ion and light-ion induced reactions have investigated understand dynamics barrier, phenomenon hindrance studied only for handful asymmetric systems. We report new functions systems 16 O+...
