Collinear versus triangular geometry: A ternary fission study

RADIOACTIVITY ²⁵²Cf(SF); calculated ternary potential energy surfaces (PES) for different positioning of the three fragments from a collinear arrangement to a triangular arrangement as a function of the angle between the fragments of ¹³²Sn+¹¹⁶Pd+⁴He, ¹³²Sn+¹⁰⁶Mo+¹⁴C, and ¹³²Sn+⁷²Ni+⁴⁸Ca. Collinear geometry favored over orthogonal geometry for third fragment.
