Is the Double Giant Dipole Resonance Process Responsible for Alpha Emission in Ternary Fission?

The Monte Carlo program built on the double giant dipole resonance model proposed by Mouze et al. Nuovo Cimento A 110(1997)1097 was employed to calculate the energy spectrum of alpha particles emitted in the spontaneous ternary fission of ²⁵²Cf. It has been found that in the case of the zero orbital angular momentum of alpha particles in the alpha decay of the fragments, the measured alpha spectrum can be reproduced approximately by the model without any adjustable parameter.
