Fission fragment angular distributions at near-barrier energies in <SUP>11</SUP>B, <SUP>12</SUP>C, <SUP>14</SUP>N+ <SUP>209</SUP>Bi

Fission fragment angular distributions and fission excitation functions have been measured for 11B, 12C, and 14N+209Bi systems at near-barrier energies. The measured fission fragment anisotropies are in agreement with the predictions of the standard saddle point statistical model. For these systems, there is no evidence for any "anomalous" behavior of the anisotropies as a function of both energy and entrance channel mass asymmetry. The present results combined with the data available for 16O, 19F+208Pb, and 16O+209Bi systems and for deformed actinide targets systems are consistent with the conjecture that target deformation plays a strong role in the observed anomalous anisotropies in actinide targets
