New results of measurements of the angular distributions of proton-induced fission fragments of 182, 183, 184, 186W in the proton energy region 50--180 MeV are presented. The results are discussed together with earlier data, obtained for subactinide nuclei 204,206,207,208Pb and 209Bi and actinide nuclei 232Th and 233, 235, 238U, for both proton- and neutron-induced fission. Similarity is noted of values and energy dependences of angular anisotropy of fission induced by protons and neutrons (taking into account a trivial effect of Coulomb factor) as well as influence on the anisotropy value of the emission character of fission of actinide nuclei and its connection with parameter of fissionability Z2/A.
