Influence of a one-neutron-excess projectile on low-energy incomplete fusion

摘要: Background: Incomplete fusion has been found to be an important contributor in light heavy-ion ($A\ensuremath{\le}20$) induced reactions even at slightly above barrier energies.Purpose: For better insight into the dynamics of incomplete fusion, onset and influence need investigated terms projectile energy (${E}_{\mathrm{lab}}$) entrance channel mass-asymmetry (${\ensuremath{\mu}}_{A}$). A rich set experimental data on may useful correlate probability with various parameters eventually develop a theoretical model code for same. Presently, there is no available which can explain low-energy consistently.Methods: The excitation functions complete residues populated $^{13}C$+$^{169}\mathrm{Tm}$ system have measured using recoil-catcher activation technique followed by offline $\ensuremath{\gamma}$ spectroscopy. evaporation identified basis characteristic lines confirmed through decay-curve analysis.Results: $xn$ $pxn$ channels are good agreement statistical pace4; this suggests population these via fusion. Some contribution from their higher charge isobar precursor decay. deduced cumulative cross section standard successive radioactive decay formulations. $\ensuremath{\alpha}$-emitting observed significantly enhanced as compared pace4. This enhancement attributed strength function that obtained $^{12}C$+$^{169}\mathrm{Tm}$ system. It one-neutron (1$n$) excess $^{13}C$ (as $^{12}C$) results less due its relatively large negative alpha-$Q$ value. Recently proposed ``alpha-$Q$-value systematics'' seems data.
