چکیده انگلیسی
The decay of various compound nuclei formed via exotic neutron-rich 9Li projectile is studied within the dynamical cluster-decay model (DCM). Following the earlier work of one of us (RKG) and collaborators (M. Kaur et al. (2015) [1]), for an empirically fixed neck-length parameter ÎRemp, the only parameter in the DCM, at a given incident laboratory energy ELab, we are able to fit almost exactly the (total) fusion cross section Ïfus=âx=16Ïxn for 9Li projectile on 208Pb and other targets, with Ïfus depending strongly on the target mass of the most abundant isotope and its (magic) shell structure. This result shows the predictable nature of the DCM. The neck-length parameter ÎRemp is fixed empirically for the decay of 217Atâ formed in 9Liâ+â208Pb reaction at a fixed laboratory energy ELab, and then the total fusion cross section Ïfus calculated for all other reactions using 9Li as a projectile on different targets. Apparently, this procedure could be used to predict Ïfus for 9Li-induced reactions where experimental data are not available. Furthermore, optimum choice of “cold” target-projectile combinations, forming “hot” compact configurations, are predicted for the synthesis of compound nucleus 217Atâ with 8Liâ+â209Pb as one of the target-projectile combination, or another (t,p) combination 48Caâ+â169Tb, with a doubly magic 48Ca, as the best possibility.
