The fission fragment angular distributions have been measured for the system 19F + 209Bi over a range of bombarding energies from 88.0 MeV to 125.6 MeV. The measured fission fragment anisotropies are in agreement with the saddle point statistical model calculations in the above energy range. Combining these data with those available for 11B, 12C, 14N, 16O and 18O + 209Bi, 208Pb systems, it is concluded that the spherical target plus projectile systems behave `normal, from near- to above - barrier energies. This observation is in contrast to the `anomalous, anisotropies exhibited by the deformed actinide target - projectile systems at near - barrier energies.
