Trajectories of three point charges are computed two-dimensionally to analyze the experimental data of ternary fission. In the case of a fission accompanied by a long-range alpha particle (LRA fission), the final value of emission angle of the alpha particle is found to depend mainly on the values of the fragment mass ratio and the ratio x, where x=D_a (distance between emission point and light fragment)/D_f(distance of two fragments at scission). The final alpha particl energy E_A is represented by the equation E_A=(a+b/(D_f^c))(x-x_0)^2+(d+(f/(D_f^e))E_α^<g(D_<f-h>)^<1/2>>, where Eα is an initial kinetic energy. The values of parameters a, b, c, d, e, f, g, h and x_0 are determined for some values of the mass ratio and the total kinetic energy in LRA fission of ^<236>U and ^<252>Cf. The distributions of Eα, D_f and the initial total kinetic energy of two fission fragments are obtained for LRA fission of ^<252>Cf. Most of fragments are ahown to have already about one-third of the final kinetic energy at scission.
