Abstract
New results of measurements of the angular distributions of proton-induced fission fragments of ^{182, 183, 184, 186}W in the proton energy region 50--180 MeV are presented. The results are discussed together with earlier data, obtained for subactinide nuclei ^{204,206,207,208}Pb and ²⁰⁹Bi and actinide nuclei ²³²Th and ^{233, 235, 238}U, 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.
