Abstract

We have measured the complete fusion, incomplete fusion, and the one-neutron stripping reaction for the $^{9}$ Be+ $^{186}$ W system, at energies not too much above the Coulomb barrier. The online and offline gamma ray spectroscopy methods were used for the derivation of the cross sections. A large value of one-neutron stripping cross section has been observed. The comparison of the data with coupled channel calculations without taking into account the breakup and transfer channels show the usual complete fusion suppression. The possible suppression of the total fusion is discussed.
