Possible influence of neutron shell closure (N<SUB>c</SUB>=126) on fission anisotropies for <SUP>19</SUP>F+<SUP>194,198</SUP>Pt systems

Fission fragment angular distributions have been measured for 19F+194,198Pt systems in the laboratory energy range from 88 to 104 MeV and the fission fragment angular anisotropy data have been compared with the statistical saddle-point model calculations. The anisotropy data for 19F+198Pt(217Fr with compound nucleus neutron number Nc=130) are in good accord with the calculations over the entire range of bombarding energies except at the highest energy point. However, the data for 19F+194Pt(213Fr with Nc=126) though consistent on the average with the calculations, show noticeable deviation at a few energies
