Exploring the onset of quasifission by measurement of mass distribution in¹⁹F+¹⁸⁴W

Abstract

Abstract. Fission fragment mass distributions for19 F+ 184 W have been measured at beam energies in the range of 85 -125 MeV. Analysis of mass distribution width indicates that the system proceeds towards the formation of compound nucleus. No signature of quasifission is observed in this reaction. These results strengthen the conclusions of our earlier works revealing the stabilizing effect of the Z = 82 shell closure against fission.
