[en] The classical motion of an α cluster inside the fissioning nucleus ²³²Th (simulating the α accompained fission of ²³⁶U) is calculated. For certain initial conditions. the α trajectories escape the region of nuclear attraction due to repeated positive interactions with the moving potential wall. This α emission was found to take place only through three narrow windows along the barrier ridge but in all possible directions. The motion seems to be nonchaotic and the domain of starting conditions for escaping trajectories is nonlocalized and has irregular boundaries
