Abstract
The interaction potential for spherical-deformed reaction partners iscalculated. The shape, separation and orientation dependence of theinteraction potential and fusion cross section of the system32S+154Sm are investigated within the double-folding modelof the deformed nuclei. The effective nucleon-nucleon interaction istaken to be the M3Y-Reid potential. The density is considered for threeterms of the expansion using the truncated multipole expansion method,which is a deformed Fermi shape with quadrupole and hexadecapole for thedensity distribution of 154Sm. It is found for the interactionpotential that the height and the position of barrier stronglydepend on the deformations, the orientation angle of the deformednucleus, and hence produce great effects on fusion cross section.The integrated fusion cross section is in good agreement with theexperimental data.
