Microscopic dynamic study of giant resonance excitation and fusion in $^{132}$Sn+$^{48}$Ca
ORAL
Abstract
In connection with experiments at Radioactive Ion Beam Facilities, we study pre-compound giant resonance excitation and fusion in heavy-ion reactions within a microscopic dynamic theory. Calculations are carried out on a 3-D lattice using the density-constrained Time-Dependent Hartree-Fock (DC-TDHF) method [1,2]. For $^{132}$Sn+$^{48}$Ca, we calculate the time-evolution of giant resonance excitation and associated gamma-ray yield. Also, we calculate the heavy-ion interaction potential and total fusion cross section and compare the results to $^{124}$Sn+$^{40}$Ca. A comparison with recently measured fusion cross sections will be given.\\[4pt] [1] Umar and Oberacker, Phys. Rev.
