FUSION OF S-32+SM-154 AT SUBBARRIER ENERGIES

Fusion-evaporation cross sections for the S-32 +Sm-154 system at bomba rding energies near the Coulomb barrier have been measured by off-line observation of the K x rays emitted in the radioactive decay of the r esidual nuclei. The total fusion cross sections were obtained by addin g the contributions from evaporation and fission processes. The fusion excitation function for this system is compared with coupled channel calculations that include the deformation of the target and vibrationa l states of both target and projectile.
