摘要

Different modes of fusion phenomena observed in the isolated experiments are not yet fully understood. To comprehend these fusion mechanisms, more experimental studies are necessary. In view of this, a new measurement of residual cross sections from the Li-7-induced reaction on Y-89 has been reported in this article within the 2.7-5.7 MeV/nucleon energy range. The gamma-ray spectrometry has been used to identify the residues Mo-93(m), Nb-92(m), Zr-89, Y-91(m), and Y-90m produced in the reaction. A systematic analysis of the complete and incomplete fusion dynamics has been carried out by comparing the measured excitation functions with the equilibrium and pre-equilibrium reaction models in the framework of EMPIRE3.2.2 and ALICE19. A strong indication of the occurrence of incomplete fusion has been realized within the energy range considered; hence the incomplete fusion strength is discussed in detail. The product yield of( 93)(m)Mo, which is a candidate radionuclide for radiopharmaceuticals, has been estimated.
