ABSOLUTE FUSION CROSS-SECTION OF 16O+186W FROM X-γ COINCIDENCE MEASUREMENTS
X-γ-ray coincidence measurement is a good method to obtain cross-sections when the evaporation residues are decaying by electron capture.In this paper, a X-γ ray coincidence measurement system was established to obtain the absolute fusion cross-section of 16O+186W at energies around the Coulomb barrier. The results indicate that this method can efficiently decline the background and the cross-sections extracted from our job are in accord with ones measured by using recoil mass separator.
