Description of light charged particle emission in ternary fission

Abstract

We consider the motion of three fragments starting from the scission point of ternary system. In the alpha‐accompanied ternary fission the initial conditions are not the free parameters and determined by minimization of potential energy at scission point. In the trajectory calculations the angular distribution and mean value of the kinetic energy of the alpha‐particles are well described in the spontaneous ternary fission of 252Cf. In the Be‐ and C‐accompanied ternary fission we found that the emission of the third particle occurs from one of the heavy fragments after their separation.
